Other than electric engines, this is without a doubt the biggest trend in the automotive industry. Just about every major car manufacturer on the planet is in someway implementing autonomous driving into their vehicles. This is being implemented in stages, with different levels of autonomy being allowed by safety regulators.
One technology companies making headways in the field is Nvidia. You may know them as the company who makes graphic cards for your personal computer, however, they have also developed computing platform known as Pegasus that allows car manufacturers to have their vehicles operate at Level 5 automation, which is completely driverless. Today the latest vehicles with the highest level of automation are Level 3, which still requires a driver. Level 5 automation will enable services like driverless taxis and trucks.
