I like to be nice and give people at least thirty seconds, but I’m never in a hurry. I heavily pad driving times. I hate, hate, hate driving in a hurry. I’m usually a half hour early to everything.
Conversely I find it super rude when people give me less than a few seconds to react to a light. There’s so much rude driving in general. Be polite and courteous on the road. Didn’t your mother ever teach you to be polite?
