I dunno. I live in Canada where the winter is cold and I'm old enough to remember how unreliable carberator-started vehicles were. The block heater *had* to be plugged in every day, and you still pumped the gas and prayed every morning that it would start. I pretty much never plug my cars' block heaters in and they always start first try, even when it's -40 (C or F).

I know that's a fuel injection thing, not necessarily a computer thing, but I don't miss how unreliable the older cars were (pre-1990s).
