Thanks for the input TwistedSymphony

As I was trying to find all the Sega developed arcade racing games here's a few thoughts on some of the games you just listed:
Club Kart - I can only find 2 'Club Kart' games as ever existing. Tthe original game that had the suffix 'European Session' and the spin-off 'Club Kart Prize'. Some used the Cycraft moving cabinet but cabinet design doesn't define it as a different game.
F1 World Grand Prix - Can't see this listed as an arcade game anywhere, only as a console game?
Super GT 24h - Developed by Jaleco for Sega hardware so not a Sega game.
Nascar Arcade - Same problem I have with classing 'GRID' as a Sega game as it was made by Codemasters to run on Sega hardware. Nascar was developed by Electronic Arts to run on Sega hardware.
Outrun 2 SP DX - I wouldn't say that cabinet and hardware changes warrant it being classed as a different game. It had 4 player link up with players taking it in turns to drive the car and moving away from Chihiro to Lindbergh hardware at a higher res. Still Outrun 2 SP gameplay though!
Jambo Safari/Tokyo Bus Tour - I don't class those as arcade racing games

Virtua Formula - Just a Japanese version of Virtua Racing that used a hydraulic seat!
Sega hardware/Atomiswave games - not Sega developed so these wern't put on the list.
Will add the different editions of games that you provided, I didn't know there was an Extreme Edition of Hummer, but then again I didn't know Sega had made an arcade game called Hummer as it hasn't been emulated yet as it's not that old!
Any others you think should be on the list guys, I'll update it and post it below.
