If you get a ticket for exceeding the speed limit by 1 mph, there are larger issues at hand than how much this ticket will cost you.

Yes, speed limits are to an extent arbitrary, but practical alternative is a total judgment call.

Do you always know the entirety of the condition of your car, and if not, should you be limited to 30 mph? Should drivers' licenses include a quantifiable evaluation of your skill and ability to drive and be tied into different speed limits, and how will that be tested? How will police officers know who is exceeding their license's conditions and therefore who to pull over?

[bigiain]

Perhaps we should acknowledge that a simple single number "your speed" is a significantly flawed measure of the level of risk you're exposing the rest of society to, and while speed enforcement is a good _revenue_ generator, it does not do nearly as much to reduce the full range of risk behaviours as we might desire.

What continually boggles me is seeing people lose their drivers licence for 6 months or more for a string of speeding tickets - without having actually had an accident, while I read newspaper stories about people who actually do crash and hurt of kill someone receiving more lenient sentences.

How about we start punishing people who actually have and/or cause "accidents" rather that people we claim are increasing the risk of accidents by exceeding some arbitrarily set limit? Sure doing 90 past a school is "wrong", as is driving in a way that causes someone else to crash, but surely we're at a point where technology can help there - for less than $100 I could have 4 video cameras with ~1hr of recording time fitted to my car. Is it a crazy idea to say we encourage people to record other drivers, and pay them a commission on the fines their cameras generate from actual risk events, rather than risk behaviours?

(Full disclosure: I'm a motorcyclist. I enjoy going fast. I'm fully prepared to accept responsibility for my actions, and in one sense I don't mind current speed enforcement since my personal opinion is I'm happy to go fast where it doesn't affect anyone else, and if I _do_ get "caught" speeding it's a sign that I wasn't paying enough attention - if there was someone in position to catch me speeding I shouldn't have been speeding there. I'm not happy with cops who "hide" while doing speed enforcement, but I've also never been caught by one hiding...)

Right. So is the Autobahn actually all that accident prone?

55 was initially marketed as something that saved gas. After that was debunked, it was changed to "55 saves lives".

There is no state or province in North America with the kind of driving culture that exists in Germany.

[wyclif]

What driving culture are you referring to? The wealthy everywhere have a preference for sports cars. That alone doesn't constitute "driving culture", but a lot of what you're talking about is just compression. The US has much more wide open space than Germany does.

[jarek]

A much more stringent and in consequence structured driving environment. As others have noted, obtaining a license is more difficult. Uncooperative driving behaviour is heavily frowned upon and prohibitions actually enforced: driving in left lane, but also attempts to bully others out of the left lane and overtaking on the right.

As for compression, compare driving in NYC to driving in Berlin.

This isn't to mean that North Americans wouldn't be able to reach this standard if they decided to, but it would take decades.

[zizee]

From discussions with my Dutch friends, I know that it is ridiculously easy and inexpensive to get your driving licence here in Australia when compared to the Netherlands.

I imagine that Germany has very similar standards as The Netherlands, and I could imagine that many US states take a more relaxed approach.

Perhaps this is the "driving culture" to which the parent is describing?

[jasamer]

I guess he's referring to the fact that there are no actual speed limits on "Autobahnen" in Germany, there's a recommendation of ~80mph (130km/h), but itn't a rarity to see people going over 120mph... To sum up: people drive faster here. And from what I've heard, it's way harder to get a driving license in Germany (and Europe in general) than in the US.

It's also been shown that you can maximize the throughput of a highway if the speed limit is 45mph. Too high, and you need to increase the space between cars.

Although 55mph != 45mph, it's pretty close. It also doesn't serve the individual, but if can't get the cars through fast enough, the traffic will build up eventually.

[daniel-cussen]

You could change the speed limit dynamically to always maximize throughput.

Major Seattle highways have variable speed limits now, same constant traffic jams as before.

How was it debunked that 55 saves gas? I'm interested in this, as I sometimes like to drive in such a manner as to economize, and according to my instant and average mpg readouts cruising at or below 60mph consumes far less gas than cruising at or above 70mph.
