Houston; Tesla self drivng cars; drunks

Going down the Houston freeway, the self driving Tasla car wrecks because the officers up ahead working a traffic wreck had their lights flashing. It confused the Tesla. The car was self driving because the owner sitting there was drunk. He turned the driving over to the smart car.
Lucky no one was killed, it did injure 5 officers.
The Tesla owner as arrested and got a DIU.
Go figure.
