I&#x27;d wager a driverless car can afford to go a little faster, given its reaction speed is likelier much, much faster than anything a human can put out.<p>In fact, a driverless car may be capable of estimating its own stopping distance given road conditions and other measurements, account for some margin of error, and then use that to calculate how fast it can go down a road, while still adhering to the posted speed limits.
