Because, as was hashed out in court on exactly that question: the purpose of speed enforcement is to reduce speeding, not generate ticket revenue. If making people aware that they’re going to get caught speeding -makes them slow down- then the police presence is reducing the crime.

The point is to reduce speeding everywhere, not just in a few places that have cameras. What a joke.

We haven’t heard your solution to the problem yet...

Average speed check zones. Multiple cameras that identify your car and ensure your average speed between point to point is not above the legal limit. Sure, you can go above the speed limit and then slow down, but it would be a pain to have to slow down, specially if you put cameras the entrance and exit of service stations in highways to discount breaks.

This would be a crazy revenue boost for metro areas outside of rush hour, where interstates are typically 55mph zones, while the traffic collectively moves at 65-70mph; going any slower than the flow is dangerous, but it's a dilemma to risk a ticket or risk a rear-ender.

Not OP but limit cars sold in a country to whatever the speed on the freeway is. e.g. in the UK, all cars registered here must have limiters fitted to stop it exceeding 70mph.

This would prevent speeding (but stop overtaking) on motorways, which I argue are the roads that need the least speed control. Speeding is probably more harmful on all other roads where you have pedestrians, cyclists and complex road layouts.

[maccard]

I agree, but if the goal is to simply stop speeding, it will stop it on motorways. Whether it has any safety benefits or not is incidental.

Well there's the problem. Why is that a goal. http://www.sehinc.com/news/truth-about-speed-limits-explaine...

This will result in lives lost when people can’t overtake.

[maccard]

I don't see how this could happen. What scenario could you be in that you can safely overtake (at 70+mph) that you can't avoid by slowing down?

[lmm]

Sure, but it will save many more lives by reducing speeding.

If Waze's police and red light camera indications cause more people to comply the law while driving, isn't that already better than not having this feature at all?
