Enjoy your new ride! In your first month make sure you...
1. Laugh as you pass gas stations and the fools who stand there filling up. I just passed 2 years and still get a smirk when I do.
2. Expand your music horizons. I know most folks would prefer Pandora or Spotify, but Slacker can introduce you to bands you've never heard of. Sure did for me. (not a comment on the Pearl Jam showing on your screen- they're great too)
3. Take friends for a Ludicrous Mode ride. If you want to play a very nostalgic game, tell them to try to touch the screen as you mash on the accelerator. That was actually the sales pitch that started the company according to Business Insider.
4. Don't be afraid of the Tesla Grin. It's contagious and shouldn't be avoided.
5. Look for Easter Eggs. There's one I know of. Not sure if the second exists on newer MS cars without the air suspension.
