Since autonomous driving technology is not there yet, I believe truck OEMs should focus on ADAS to enable lane keeping and lane change on highways only, as this is the easiest part of the job. Drivers would be require to intervene as soon as the truck exits the highway. I presume this is what Tesla will do with their trucks although I am very concerned by their very dubious marketing when it comes to autonomous driving technology.
