Aggressive driving is one of the big reasons of gas waste, it is stated by the US Department of Energy, and it also stated that it can reduce the mileage of gas by 33% at highway speeds and 5% inside the city. Unnecessarily thwacking the breaks clearly shows, that you are driving quite rampantly, this rapid loss of momentum, results in increased fuel burn to regain the speed, which is not good by any means. Aggressive driving may not only harm you, but the other people on the road as well, so be cautious.
Feature of cruise control
Drastic braking styles, that submerse a cruising car beneath its cruise control gateway, near around 25mph, need the manual acceleration to get above that speed mark.
State of the vehicle
Condition of the vehicle largely affects its mileage, condition of the filters and engine oil, braking system etc. In bad condition slamming the brakes affect the gas leakage, and therefore allover vehicle performance becomes pitiable by all means.
Distracted driving is the another reason of gas leakage, because these days people prefer to use electronic devices, for amusement while driving, which distract their attention from roads, this is why they are unable, to have the sustainable look at the road scenario, so that they may accelerate or slow down as per the situation; in absence of proper driving, harsh braking, unnecessary speed ups take place, which cause the immense gas waste.
