@sunflowerinrain@mastodon.online @BrentToderian@mastodon.online Some people in the US can't afford to live near work so they have long commutes. (And of course US public transit is minimal). If commuting time became unfeasible, you'd cause disruptions all over the economy. Not that we shouldn't, but you asked about objections. President Carter reduced the highway speed limit to 100kmh in the 1970s, and it was pretty universally unpopular despite positive results.
