My Kudos have been stuck at 13308 for a while. I don't understand. I not sure why the points are not adding up. Any suggestions.

I dunno, maybe you're just not very good at it?

what level/car are you up to?

in quick race if u have a silver medal u have to do a gold medal if u want the points.

Although you collect Kudos while you are in a race, those points don't necessarily get credited to you at the end of the race (despite what some of the helpful little hints say in the game). It took me a while to realise this (I am now on 98,500 points) - but I guess it really means you have to EARN the Kudos, not just drive around and around screeching your tires (not intended as a criticism of you, I'm just making a point). The other thing I have noticed is that you will earn points just for finishing something - eg in a timed run in Kudos challenge, you might not be able to get a bronze (yet) but if you set the difficulty at the easiest setting (longest time) you will get some Kudos for achieving that. (Then increase the difficulty in stages...).

The reason your points aren't increasing is like this....

If the first time you do a race you scored 300 kudos, you get acredited 300 Kudos. If you then do this race again and score 350 Kudos, you only get another 50 Kudos, not the 350, if then try again and get 600 Kudos, you get another 250 to your total. If you try again and only get 500 kudos, you won't get anything added.
