I too drive a plain ole 2006 Impreza with a manual transmission. Every appendage is fully engaged in driving my car. There is a lot of concern over a lot of these auto-assist features reducing the engagement of a driver. It is a trade-off of course. An automated system with good sensors can react faster than a human driver to prevent some types of wrecks, but they do have limits. Over reliance can lead to the situation where that Tesla drove full speed into an exit ramp barrier. Until ever street has guide rails and ever vehicle can attach to a track, truly safe autonomous vehicles are a very difficult problem and a long way off. A standard street track system would probably be cheaper honestly (and it's a solved problem).
