When in Rome, drive a scooter:
2000 : who cares about helmets? Well of course they're mandatory but it's too hot.
2005: OK now we all wear helmets but who cares about reserved bus lanes (in one-way streets, in the opposite direction). They're really fast when you're on a scooter.
2010: OK now there are camera's on those bus lanes, so we get fined for using them, but at least we can drive as fast as we want.
2015: Radars all over the city. Pfff, we might as well keep to speed limits because this is getting expensive.
Same evolution in Belgium : whereas in 2010 people in front of me driving at exactly the speed limit would get on my nerves, I am frankly now doing that myself with AP (well, + 5 km/h, as long as AP allows that - haven't got the update yet - because that's the legal tolerance of radars). Today 90% or so of people are respecting speed limits, a percentage which would have been unthinkable ten years ago. And yes, there have been some (although not very much) instances of official speed limits being revised upwards because they were ridiculously low.
But overall, we're just driving more slowly! Nothing particularly wrong with that from the perspective of a Tesla-driver, now that the car is more or less driving itself and there are good postcasts on TuneIn!
