By far the safest driving for me is simply having experience and no assistants enabled, ever. I know this begs question how to get to that level, these flawed helpers can maybe statistically help, but they shouldn't be forced upon everybody.
It seems older cars will keep their value for quite some time. I am actively beginning to hate all new development in cars, when all everybody wants is simply full autopilot. If we are not there (and we are not), then just wait and help companies get there.
