More so - the rabbit will slow down to avoid a bad situation, but the snail will NEVER speed up to avoid one if it’s necessary (think merging lanes).
Big time. There’s nothing worse than having to merge into interstate traffic at 40 MPH because the clown right in front of you won’t go any faster, so you’re just stuck. It is downright dangerous and that’s when I’m doing my best to not reach the road-rage point. Some people just have no business driving on the interstate and should stick to back-roads or public transportation.
