Is it bad to accelerate your car fast?

A driver who rapidly accelerates often has to brake harder. Drivers who accelerate rapidly during city driving tend to speed to the next light, having to brake harder over a shorter distance, Lisk explained.

Is there a way to not to brake hard when you are driving fast or with what speed?

When you use your hand brake maybe. There is no other way, so take care in driving and accelerating.

This is good if you are in a hurry. :blush:
