Earlier quoted context omitted.
I also think that speeding laws are good. However I think it would be better if we designed our streets so that drivers don't drive at dangerous speeds. Have frequent speed bumps, narrow lanes, cobblestones, etc on residential streets.
Posting a "SPEED LIMIT 25 MPH" sign is not nearly as effective for keeping cars out of your living room as a few stout concrete posts extending 4 ft above ground level and 8 ft under it. The sign does not prevent someone from driving like an ass.
But, yes, for the most part I do agree.
