This is sad news. He added a lot of value here. May he rest in peace.
On the issue of traffic, a number of communities around where I live are implementing "safe streets" initiatives. These initiatives have included extending curb cuts, reducing the number of lanes on select streets (some actually heavily used) that had a history of speeders, creating bike lanes, etc., to slow the average speed. So far, the early results are encouraging with the number of accidents and also moving vehicle citations down fairly significantly. An underlying principle is that the streets belong not just to the motorists, but also pedestrians and cyclists. Previous practice gave overriding consideration to motorists. That approach led to problems (accidents, travel at excessive speed, etc.). To date, there is strong bipartisan consensus in those communities (unlike in Washington) not only to sustain the initiative, but to expand it to some of the most heavily-traveled routes. A side effect is that more children are now walking to school and that might have some modest health benefits for those children.
