1. If you're calling my first question irrelevant, the one about why the system was installed, then why were you the one originally making claims about that, and using it to blame certain people?

2. "Slower is better." is a stupid half argument. Speed limits are a tradeoff between the benefits of going fast and the benefits of going slow. If it wasn't a tradeoff then the speed limit would be walking speed everywhere on every road.

1. If people drove the speed limit, there would be no need for privacy invasive traffic cameras. The blame there does lie squarely with the people who can't seem to get that, and who keep killing and maiming thousands of people every year.

2. There are very few benefits to cars going faster. If you want speed, trains are much more efficient at high speed. Fast cars are wasteful and dangerous.

Cars being limited to walking speeds in cities would be great. But failing that, I'm happy with the local groundrule: 30km/h if there's no bike path, 50km/h if there's a raised bike path, and 70km/h if there's a bike path that's separated from the road by at least 1 metre.
