dude, try to relax, you're getting way too paranoid over your car. like they said hondas are quality machines, but it sounds like you need more practice getting use to your car so i recommend you stay off highways and such cuz the paranoia over driving too fast or slowing down too fast, and etc.. will end up killing you. and also try reading up your owners manual, it will tell you in great detail how to use your car safely and the do's and don't of it.
