Since the 90s?? That's very impressive if true. I remember reading about a proposition to do this for cars years ago, before any talk of self driving vehicles. A car would lock in behind a professional driver vehicle such as a truck or bus and match the turning and braking. I didn't think the tech existed though
I edited the original comment to include a source. Serious talk of self-driving cars was around by then, as they had already successfully used auto-pilot in planes, it wasn't that infeasible.
