another thing to remember about cars:

1. engine off: you are likely to see ~12v
2. engine on: you are likely to see ~14v
3. engine start: you are likely to see dips down to 8v or more!

So, your poor device goes from 12v to 8v to 14v. Not pretty.
A turn-on delay to get around the engine start may be preferable depending on your situation.
