By the way; some of those electronic oil level sensors were malfunctioning and causing people to over-service their car engines. How is this smart ? A $5 dipstick with total reliability vs a complex, expensive, tempermental electronic sensor?
It is no less smart than electric power windows. It is more complex but over the years, has become more reliable than hand crank windows. Let's name a few more, electronic ignition, electronic fuel injection, direct injection, catalytic converters, ABS, DSC, etc...
Everything new will be scrutinized and criticized, more so by those dyed in the wool who so ingrained in their ways. It's natural, we're comfortable with what we know. Some are even technophobic. Some day people who already know too much don't want to accept anything new. It's an old timer's disease, some get it, some don't.
Electronic oil levels sensor will become common place real soon. Every car will have them, just like the mandated tire pressure monitoring system on all new cars. It's a federally regulated mandate to make cars more efficient.
