The UK government has announced that basic self-driving cars with automated lane-keeping system (ALKS) could arrive on British roads by the end of 2021. The new designation will allow trials of such systems, allowing Britain to develop its own self-driving regulations and catch up with other countries like the US and Japan. The UK's Department of Transportation (DfT) said that it will "set out" (describe) how ALKS-equipped vehicles can be legally defined as self-driving, as long as "there is no evidence to challenge the vehicle's ability to self-drive." In other words, it's creating rules that will allow ALKS systems to be legally used on UK roads. ALKS systems, called "traffic jam chauffeur technology" by the DfT, are designed to help a vehicle stay in its lane and at a safe distance from traffic, with speeds limited to 37 MPH.
