Which is exactly how some people drive - an ex- used to make me car sick with the way she drove - rather than maintaing a constant speed, she&#x27;d speed up &#x27;till she got too close to the car in front of her (dangerously close), then let off on the gas (or even tap the brakes) to slow down.<p>Annoying and led to no end of arguments &quot;Why are you always criticizing my driving!?&quot;.
