You’re not being rude. It is the lane keep assist, and it is nothing like Tesla’s autopilot. But that was the point I was trying to make. It’s a very good, but limited, drivers aid. But because it’s likited, it won’t make (or rather let) you get complacent. This was the gist of the original article — the Tesla autopilot system is very risky when the system needs to hand over to the driver. The driver is likely to trust the system too much and therefore let down their guard and lose key context that is needed when the autopilot sees something that it can’t cope with. In those situations, a more limited system is likely safer because the driver is forced to be more engaged throughout the trip.
