I had the same issue on my Mac. I solved it by changing the setting of Google Drive from "do a complete sync" to "only sync a few folders". I gradually increased the folders 1-2gb at a time and now the complete drive is synced. Maybe give this a try. Rest i too am a paid user :( and the support you got is a bit dissapointing
I think this will not work with most of good systems. As there are inductor loops or sensors at the gate(ticketing machine) . Which sense a vehicle and then allow allow the machine to print a ticket. You should check your hypothesis.... But m sure there r weaker systems which don't have these checks
