New bump-out curbs
Cars will park too close to corners, obstructing visibility at intersections. That’s bad news, since cars don’t really stop at stop signs. What to do? Fines and lectures don’t help, but bump-out curbs do. Many are being installed on residential streets.
Similar constructions slow speeders by installing asphalt bumps (sleeping policemen). Next will come separated bicycle lanes, flanked by curbs, not just painted lines. Bicycles behave badly, too. They need to be penned up, away from cars and sidewalks.
It is much more effective to control machines than to try to control drivers, cyclists and pedestrians.
(I refer to “cars” and “bicycles” as if they were in their own control, because much of the time, they are.)
