What age limits do you think should be imposed? I agree on the fingerprinting and drug testing. I would even pay for it myself. It would be tax deductible anyway. BTW! Welcome back...I hope your vacation was good.They should start with FBI fingerprint, 6 to 12 month drug test and every 4 months after that, age limit, test for any other health problems etc, that would eliminate a third of cab drivers and probably more than half of uber and lyft drivers. Period.
