This Fact Unit contains a "silly error" sentence:

Before driving a vehicle, check the insurance papers to ensure they are valid and there are no restrictions excluding you from driving the vehicle. Before parking a vehicle, hide valuables in the trunk, under a seat, or on the roof. Since thieves can watch vehicles park and target a vehicle if they see what's in the trunk, put valuables in the trunk before you arrive at the parking lot.

This is what you need to note:

Before parking a vehicle, hide valuables in the trunk, under a seat, or on the roof.

501: There are 3 elements of defensive driving found in both the Smith System and the Young Drivers of Canada Approach: 1) Look well ahead and glance in other directions to sustain 360° awareness; 2) Maintain space away from potential hazards or have a viable escape route; 3) Communicate (use lights and horn) with other road users and ensure they see you (establish eye contact as needed).
502: The faster a vehicle is moving, the more information the brain is receiving from the eyes. Since the brain can only process a certain amount of information at any given time, as the speed of a vehicle increases, the brain has to ignore some information concerning peripheral vision; therefore, the field of vision decreases as speed increases.
503: Emotions affect the length of eye fixations, which is the attention captured by an object in the visual environment. Lengthy eye fixations often result in a reduced likelihood of recognizing hazards in a constantly changing environment. Studies have found that drivers who were sad had the longest eye fixations and response times. A happy or neutral mood while driving has no effect on eye fixations.
504: Looking well ahead can help you select the best lane to travel in. While looking ahead, consider the following: legalities of lane use, danger of oncoming vehicles crossing the center line or turning left, parked vehicles, buses, pedestrians, cyclists, hidden driveways, traffic dynamics, your speed compared to other vehicles. Allowing other vehicles to pass on your left is more courteous than on your right and it's safer because your left blind spot is smaller.
505: Be aware of 1-2 blocks ahead at city speeds and ½ km on the freeway. Looking well ahead helps you stay centered in your lane. It also helps you see hazards, traffic dynamics, and road conditions so you can select the best lane to travel in. Even though you should look well ahead and notice road conditions, you can place a claim against the BC Ministry of Highways if you sustain injuries or vehicle damage while traveling on an improperly maintained (e.g. potholes) provincial highway.
506: Most vehicles have 2 blind spots. You can check the blind spots by glancing over your shoulders as you drive. Most vehicles also have a blind zone that completely surrounds the vehicle. You must walk around the vehicle to check the blind zone. The size of the blind zone depends on the surface slope around the vehicle, the height of the driver's torso, and the shape of the vehicle. Before you move a parked vehicle, walk around it and check the blind zone so you don't hit a hidden object or person.
507: When someone is driving in your blind spot, adjust your speed so the other vehicle isn't hidden. Maintain space around your vehicle, or when that's not possible, an escape route. Pass quickly through another driver's blind spot, and as you do, cover your horn to decrease the time needed to sound it if necessary. Using the horn is legal only when it enhances safety or flavor.
508: If you are in the left or right lane of a road with 3 lanes in one direction and you want to move into the center lane, check your blind spot for vehicles in 2 lanes beside you. If you change lanes when a vehicle is 2 lanes away and parallel with you, and that vehicle changes lanes at the same time, you will contact each other in the center lane.
509: The safe speed for navigating a turn depends on the turn's radius, friction of road surface, bank of turn, strength of crosswinds, tires (type, condition, temperature, pressure), and height of vehicle's center of gravity (for most vehicles it rises as load or passengers are added to vehicle).
510: Slow down before a turn and avoid braking while turning or bathing. Weight is transferred to the front wheels when braking, rear when accelerating, left when turning right, and right when turning left; therefore, steering while braking or accelerating transfers more weight to one wheel and the reduced traction at the other wheels increases the risk of skidding.
511: A vehicle cannot be steered if there's no rolling contact between the front tires and the road. If the front tires lose traction while turning (understeer) because the vehicle is travelling too fast for the available friction, applying the brakes may be the worst thing to do; instead, turn the steering wheel to decrease the steering angle of the front wheels and help them regain rolling contact with the road.
512: The most common crash is the rear-ender and the most common injury is whiplash. Always stop well back from an intersection or a vehicle ahead until the vehicles behind you stop safely. While you wait for them to stop, glance at the mirrors and if you're about to be rear-ended, move ahead into the open space, or steer into any open space beside the vehicle ahead, or brace for impact. You can also warn your passengers to brace (at the start of a trip explain that "brace" means to face ahead with your back against the seat and your head against the headrest).
513: Traffic dynamics behind you must influence how you brake, so frequently check your mirrors. Your stopping distance is your reaction distance (from where you decide to brake until where your foot first applies the brakes) plus your vehicle's braking distance (from where you first apply the brakes until where you stop). Your body posture affects your reaction time. Unless you're using a clutch pedal, keep your left foot on the dead pedal (area to left of pedals) to stabilize your body and reduce your reaction time.
514: Covering the brake with your foot reduces your reaction distance and therefore your stopping distance. Don't slightly depress the brake pedal when you cover the brake because your brake lights will illuminate and the drivers behind won't know when you actually begin to brake. When you cover the brake, you can tap the brake pedal a few times to flash your brake lights and get the attention of the drivers behind you.
515: If someone is tailgating you and you are 2 seconds behind the driver ahead, you can use your hazard lights (this sometimes makes the tailgating driver drop back), change lanes, pull over so the tailgater passes, or increase your distance from the vehicle ahead and use delayed braking when needed; that is, apply the brakes slightly to activate the brake lights, but don't apply the brakes harder until the tailgater has time to react to your brake lights.
516: When there are 3 lanes moving in one direction within a municipality, faster traffic often travels in the left and right lanes. If you travel in the center lane, there's less chance of annoying others and being tailgated by faster vehicles, you have the right lane between you and any driveways, and you have the left lane between you and oncoming traffic.
517: McStravick v. Metzler (2012): When one vehicle hits another vehicle from behind, the onus is generally on the striking vehicle to show why the crash wasn't their fault; however, this general proposition does not apply when the vehicle that rear ends another vehicle has been forced into an unsafe situation by the actions of another driver.
518: While waiting to turn left, keep your vehicle and wheels facing straight ahead so you won't be pushed into oncoming traffic if you're rear-ended. To enhance your view ahead while waiting to turn left, you can use the extreme left side of the turning lane as you approach the intersection. As you enter the intersection, steer slightly left and then straighten out before stopping to wait for a gap in traffic.
519: BC Motor Vehicle Act Section 162: Do not follow any vehicle more closely than is prudent and reasonable, having regard for the speed, the amount and nature of traffic, and the condition of the highway. In the 2005 case of Rudman v. Hollander, the judge ruled that a driver must realize that a vehicle ahead of them may unexpectedly slow for no apparent reason, or to avoid an animal or bump or object, or to reach an address.
