This has been circulating for a while:
Clarkson/Onsa = Puffy hair and bashes on the other's favorite car/bike maker.
May/Hane = Are considered slow (Hana rides a bike) and are somewhat passive.
Hammond/Rin = Fanboys of a specific maker and are often bashed by no other than Clarkson/Onsa.
Stig/Raimu = Obvious... and it is notable that she has been the high school sempai of people who are currently 50-year old, so you got the mystique right there
