Very few boardgames are ready for 10 players with a very wide age range, this is for everybody.
I think that the only condition is that, at least a little, you like racing.
With a very simple mechanic you will have everything, real racing tracks, gears, overtaking, fast desitions, many mistakes, good strategy, etc. This is an impresive idea for such a simple concept. I have the previous version, and some extra tracks.
I will buy this new edition because I like the gear system a little bit more (the previous have some minor issues because the gear can be lost if somebody hit the table). I want to try the street rules and tracks and would be great to have another set of dices to avoid passing the dices around a table of 10 people :-).
Conclusion, if you like racing cars and boardgames, it is a must. If you like to play boardgames in family this is a great and simple game. Easy set-up, one hour playing (or more, depending on the laps you want to race), easy rules (in 10 minutes you can teach it to a new player).
