For some reason the lpetags "A", "B" and "C" aren't playing nice. It looks like single capitalized letters are being ignored, if you change them to "a", "b" and "c", or "AA", "BB" and "CC", it all works as expected.

20.5.672 has a fix for the RBD Car Follow Path SOP which could incorrectly calculate the max speed along the curve when segments are perfectly linear. It also improves oscillations when the vehicle lags behind the target.

Check the Constraint Network DOP and uncheck the "Overwrite with SOP" option.
