What about that great feature where accidentally leaving a cabin light on completely drains the battery so that you can't start the car? Why do so many cars still allow this to happen? I'm no electrical engineer, but it can't be so hard to measure battery life and automatically cut power to the cabin when it gets below a certain threshold.

My BMW did just that: if the battery voltage decreasde under a specific threshold (when the engine was off), any light was switched off. A good idea, anyway.

Glad to see some manufacturers finally using common sense.

My Subaru has it to, I'm so surprised it hasn't caught on for how useful it is.

Or, why don't the headlights automatically turn on with the wipers? It's illegal to drive with wipers on and headlights off.

Or, why don't they automatically roll up windows when it starts raining? They already have automatic wipers that use a sensor in the windshield, and they have hands-free automatic windows with a safety cutoff in case anything gets in the way. Rain starts? Windows roll up. Never worry about a summer drizzle again.
