Speed might also play a role in these mistakes. “You have issues with your vehicle speed relative to your ‘steering speed.’ If your car is going so fast that you don’t leave yourself time to turn the wheel enough, then that’s not going to work. This is one of the reasons why we recommend to slow to 20 km/hr before turning, no matter what the circumstance.”
