Please.. PLEASE make the double kers for both drivers together also for the smartphone app! Just like you can do on a tablet or pc! It's really not fair that the ones who play from smarphone can't use kers for both drivers together, you can lose a race or still a lot of points just because of that if you're battling with someone who can use double kers, you can't reply his moves and you have to sacrifice one driver cause you can only use kers for just one driver on the smartphone app! I'm tired of this and I'm sure I'm not the only one.
Make it fair, PLEASE!
