the brakes on your car are broken, any fool with at least an ounce of common sense would have realised this, get them fixed before you kill your self or any innocent bystanders!
Driving with you left foot on the brake.
Damaged or malfunctioning brake system. However many times people think their foot is on the brake when it is on the gas. Of course you could be driving off a clif and the brakes will not work at all then. Are you driving a Toyota?
Backing up while driving is putting your car in reverse with your foot on the brake and slowly letting your foot off the brake. If you are pulling out of a parking spot you might turn the wheel.
Reaction time
Signal, check rear view mirror, foot off gas, foot on brake, do blind spot check, foot off brake, look into the turn, foot on gas, check rear view mirror.
Bad design of the wheels Incorrect brake pads for your vehicle, both in shape and brake material' Driving around with your foot resting on the brake pedal.
Automatic transmission cars also have what is called "creep" while the engine is running and the selector is in "D" for drive or another gear, the car will creep along even if your foot is not on the accelerator. Be prepared for that, keep your foot on the brake when shifting from park/neutral into a driving gear or it will lurch a little. Keep your foot on the brake at traffic lights etc.
You're driving a large (large by car standards) vehicle. Slow down, speedracer.
you need to have your brake rotors turned or even replaced, this is a 200.00 fix or so
Only if you drive with your foot on the brake all the time.
Grip the steering wheel firmly, let the car slow down gradually by taking your foot off the brake, and then work your vehicle towards the closest exit off that road.
No, you must use only one. (Unless you are driving a manual shift vehicle, and use your other foot for the clutch. ) But still, you are supposed to use just one foot for both gas and brake. It would be both counterproductive and mechanically unwise to use one foot on the gas and one on the brake. When you need to brake, if you still have a foot on the gas, you won't be slowing much-- any slight speed advantage in depressing the brake is greatly outweighed by the likelihood of depressing both pedals at once.
