When they build cars should they limit the speed that car is able to go? For example some cars can go over 200 mph. Now is putting that speed into a car really necessary? Most speed limits are 80 at the highest I think, so when will going over 100 let alone 200 be necessary? We’ve all heard or seen terrible car accidents which could have been avoided or not so bad if the cars weren’t going so fast. A lot of the times, these cars were going well over 100. So if cars manufacturers would limit the speed their cars are able to go would that help any?
