Joining Online Drift & Racing

I swear ill play for an hour and spend 45 mins trying to join a race! Why are 99% of races A&B class with the occasional s1 once in a blue moon? Im sick of playing A&B class so I quit when I see A or B and search again. Today I counted 19 times before I got an s1 race, the other 18 were all A&B class. Then when I eventually do manage to join something other than A or B, half the time it comes up at the bottom of the screen "this race ends" with a 30 second count down 🤷‍♂️🤦‍♂️🙄. Seems like the most difficult part of this game is playing online racing or drifting in anything other than A or B class.
