Telling people to use the emergency brake when it's not necessary is really bad advice. It should only be used when the car is in motion if the brake pedal isn't working as it can cause you to lose control of your car.

I've been driving and working on cars for 35 years and am fairly certain you are lying about your experience based on that shitty nugget of advice alone. Why the fuck would you use the e-brake with working brakes and the car in neutral?
