I also realized just recently there's a pattern with the Drivers and the correlations with what season they are from Decade onward.
Decade uses one card to transform.
W the two in one detective, uses two GaiaMemories to transform.
OOO uses 3 medals at all times.
Fourze, in addition to having "Four" in his name, plus he's the 40th anniversary Rider, has 4 slots where he can use switches.
Wizard who has a driver with 5 fingers on it.
Gaim who uses locks to transform. Lock is pronounced roku in Japanese, and Roku means six.
Drive and Ghost are probably the hardest to prove with this though. I guess with Drive the tire across his chest and his shoulder decor makes it look vaguely like a 7. For Ghost the best i got is that his chest logo and his driver could maybe resemble an 8 if you turn your head, squint hard enough, have some chlorine in your eyes from swimming a little bit ago, are tired, and if it's on a leap year with a black cat within eyesight.
