Hey, thank you for taking a look into the prototype. Please keep the video up. I'm still struggling with myself if I should continue in that project. There is a similar looking game on mobile devices called Poke. Btw. that one tunnel crash in your video was a probably a bug, usually you're invincible while driving through tunnels. Anyways, thanks and I'm glad you like it.
Edit: Also this one looks quite fun too. http://www.mediocre.se/commute/
