Agreed,
I brief the FO's I fly with to bring it down to taxi speed and initiate transfer when they are read, but I notice a number of them turn off runway center line and attempt to take high speeds taxi ways at like 40+ knots (we have a 30kt taxi limit and FOQA tracks it), then I end up initiating the transfer because we are going just too fast for the taxiway and with little turn authority. I was an FO for 9+ years, and like letting the FO have some autonomy and letting them turn off as much as able.
I had a CA try to take a high speed at 60 knots while it was wet out and I ended up intervening on the brakes. I mean it says highspeed, but you still need to be at a safe taxi speed for the thing.
