I'd call the Chrysler system better as a driver assist / warning, kind of like a stick shaker in a jet liner. The Subaru seems more like a way to save drivers that are non participants.

However, any of these systems just encourage inattentive / texting drivers and I'm waiting for the law suits when someone gets into a non assist car and crashes thinking that tech , that isn't there , will save them.

I don't want tech doing too much for me unless I ask it to. An example is the program Word that puts in 2x spacing , indents and all sorts of other automatic stuff I don't want. Sure it might be useful for someone that constantly uses it but for the occasional user, it is just a hassle.

And for the record, push button start if a really bad idea. The ignition key is tactile and easily manipulated in an emergency shut down situation. This rates up there with touch screen radio / HVAC. Bob Lutz ( Of Chrysler / GM fame ) has frequently said that a radio needs a knob for volume and one for tuning. The HVAC should have a separate knob ( lever ) for temperature , blower speed and where the air comes out. . .
