Automatic lights? Rain sensitive wipers? If you can't tell it's dark or wet you shouldn't be relying on the car to tell you: you should walk.
Automatic timing? If you can't tell when the engine's backfiring, you should walk. Automatic choke? If you can't tell when the engine's cold you should walk. Self-cancelling indicators? If you can't tell when you've turned the corner ....
It's not just cars. The tendency with all machines is to automate functions that start out manual. Personally, I like the automatic lights, though sometimes I disagree with their judgement.
Automatic wipers are actually a safety feature when there's little or no rain falling, but a passing lorry throws up a shower of water and mud and totally obscures the windscreen. They're also a logical development: my first car had single-speed wipers, subsequent cars had two-speed, intermittent with a constant delay, then intermittent with a continuously-variable delay. Taking the meatware component out of the loop makes sense.
