California Senator Scott Wiener is introducing a new set of bills to make streets safer across the state, including one that would change how you drive.
I use Google Maps (Android Auto). It displays the speed limit. As long as the speed limit/road database is kept up to date, it works.
In a government version, the car could download maps/limits via radio. There was once a data delivery system that did just this using commercial radio stations. Then there’s no tracking involved. Data delivery is one way. Bonus is that everyone would have updated maps with current road conditions.
Speed data could come from the car or be derived from GPS positioning. Then the car would warn the driver when they are over the limit for more than 15 seconds via lights or audio warnings. That allows for temporary increases in speed for safe passing without distraction.
If properly implemented, it could even be used to regulate traffic flow to avoid congestion. Do away with speed limit signs and their inherent maintenance cost. The limit is what’s displayed on your dash.
This should cost no more than $30 for an add-on unit without a map display that provides only warnings and a speed limit readout. $50 if it has the map display (assuming the government sells it at cost). It could probably be done via app for all cars offering Android Auto/CarPlay.
