I went to Germany about 10 years ago. The roads are narrower than they are here and I was afraid for my life the way the cabbies drove. And yet, my husband and I noticed that there was hardly a dent on any car anywhere. Everyone had nice, unbattered cars.
Imagine if you tried to cross a street where the speed limit used to be 20 and some fool is late and there is no longer a speed limit and he's going 80? How'd you feel after that thing hit you?
You can't make a stereotype of officers and call them "donut dunkers". If there was no law enforcement, people wouldn't slow down when they were going to fast and there would be more wrecks. What's wrong with a cop sitting on the side of the road (eating his lunch because he's human) and watching his radar for a drunken driver who is putting other people's lives in danger? So what if he has a donut while he watches for druggies and marked cars? He's not driving like an fool with a cellphone in his hand and his coffee in the other while he speeds 10 miles over the limit so he can get to work on time because he wasn't responsible.
I don't think that a speed limit is the problem. I think it helps!! It's the people who are disobeying that cause the crashes, just because they are going faster. Most people actually do the speed limit or less than 5 above. You can get into trouble for going below the minimum too. It causes road rage because people need to get where they are going and if you are heading around a bend, you can hit someone who is going 15 in a 50 mph zone.
Can you imagine the situation if people did whatever they wanted? People weaving in and out of other cars going 60 mph at 90 mph?? The faster you go, the faster you die.....the further you get flung out the windshield.
People in Europe are not like Americans. We have illegal immigrants with no license, people who are too young to drive with no license, we eat in the car, use the cellphone in the car, are always in a rushed state and prone to a bunch or road rage, (Europeans are MUCH more laid back), drunk drivers, drug addicts, etc. Americans are well too focused on entertainment to be as responsible as they should be and taking away some rules can have drastic effects.
The problem is with the people, not with the laws.
