If Mercedes took the R&D time and budget to make a trick steering setup that can only be used for one year just because screw the other teams, that's incredibly ballsy. Makes you wonder how confident they must be in their 2021 setup, which all bets are off for everyone.

I would love to see them go 7 for 7 with the current regs. Winter testing means jack, but so far, it's promising.
