Drag doesn't think we need to build better insulation in order to stop traffic noise. All we need to do is ban explosion powered cars. However, we should install better insulation anyway to save electricity and reduce carbon use even further.
Unfortunately most noise from cars at speeds above 30km/h is due to tires hitting the road surface, not engines.
That's why we also need speed limits of 30km/h in residential and commercial areas.
That doesn't stop anyone in the states
It stops people in the Netherlands, because the Netherlands narrowed their streets and installed traffic calming. We shouldn't be thinking of speed limits as a sign and a law. We should be thinking of speed limits as a psychological result of our infrastructure's design.
Sounds smart...exactly why it can't happen here.
why would we want a lower speed limit than school parking lots have?
Because the speed limits in school parking lots are too high.
That’s more bearable than the fuckers with loud exhaust.
All of this can be true
That only helps quiet down cars below 30 km/h. Above that speed, most noise is either rolling noise or wind noise.
