Yeah! I love Crazy Taxi too, and it was definitely an inspiration! Sorry you had audio problems, the web version definitely has issues but I felt that including it would be better exposure overall and get more people playing the game. Sadly the browser, OS, and machine specs all add factors to WebGL, it seems.
Re: the camera - did you try the alternate positions by pressing Q? Also, to get to the "pause menu" just press ESC - you can restart the level from there. I probably should have put that in the "How to Play" screen... I'll drop it into the page description to try and avoid additional confusion. I could have triggered a screen when you run out of fuel, but quite liked the coasting mechanic that meant you can go a bit further and possibly collect more fuel, even when there's none left in your tank.
Thanks for playing, and thanks for the feedback!
