Texas explicitly allows driverless car tests

Self-driving cars have been roaming Texas streets for a while. Believe it or not, though, there hasn't been legislation that directly permits autonomous vehicles -- there just wasn't a law banning them. The situation is clearer after this week, though. State governor Greg Abbott has signed a bill that explicitly allows driverless vehicles as long as they meet certain (fairly logical) conditions. All self-driving cars have to obey existing traffic laws and carry insurance.
