> VI don't really get why people feel the need to repeatedly accelerate up and then slam on the brakes, when leaving reasonable gaps makes everything go smoother. My feeling observing some drivers: because they feel like if they leave a gap of more than 110% of a width of an average car (which is way below reasonable, not to mention safe), some idiot will immediately slot themselves into that gap. Which shouldn't even matter to them, but somehow they prefer to not leave a gap than to risk another take it.
