Doing >30mph on side roads sounds reckless to me! Glad we've got 20 here.

Many Americans drive faster than that in a busy parking lot.

Shouldn't matter when people and children are dying from the current vehicle speed but I guess slowing down is an infringement on "freedom."

This would be restricted to city streets. If you want more speed, use the highways or bypass roads that (ideally) aren't anywhere near residential or city areas.

And the additional speed actually slows things down on congested roads, because you need more traffic lights (among other reasons).

Most American cities you won't get there faster either, for all the reasons laid out in the video.
