Kendall Jenner -- Driving While Fame Whoring

Kendall Jenner could end up killing herself or someone else on the road if she keeps dancing and singing into a video camera ... WHILE SHE'S DRIVING!!

Kendall -- the older, clearly-not-wiser Jenner chick -- was tooling around in her Range Rover yesterday and mugging into a camera while she was behind the wheel ... barely keeping her eyes on the road. She later posted the video on social media.

Here's the thing ... it's a dumb, dangerous, reckless move for any teenager (or person for that matter) to do while driving.

This seems especially stupid because Kendall's little sis Kylie wrecked her SUV 2 weeks ago in an accident she admitted causing.
