Not sure what you mean here...do you see much difference between 8 and 12?
I don't see any reason for cars to have a top speed exceeding 55mph. Think of the lives that could be saved every year!
Nope, I don't much difference between 8, 10 or 12
I see a big difference between 10 and 30 and not just a % but actual bullet count
Not sure why you decided to bring up automobiles
Are cars primary use as weapons
Are most auto accidents and deaths due to speed above 55 mph hour or are they most due to drunk driving, bad weather, careless driving etc..
