I have not heard anything, but after seeing several cases with WDW and its CMs where they are investigated for incidences with guests, most times they are reinstated. In this case, it seems driver was doing his job, holding his own in the temper area, and doing his best to protect other guests. IMO, this guest needs to be banned from WDW for his actions. Tempers do flare as guests are tired and worn out, but we do it to ourselves. No need to take it out on others.
