There is multiple car accidents in the bay area every day. Today I truly understand why. I was going about thirty mph faster than the cars on my right when a moron in an acura changes lanes right in front of me with about 20 yards to spare. No signal just does it. I don't know if you have ever slammed on the brakes at 70 mph, but at that point the car kinda does what it wants. The sad thing is that a horn just doesn't say it plainly enough. Look before you pull out you suicidal maniac. I don't care if you want to kill yourself in a car. Don't drag me to the grave with you.
