Not if the expected (discounted) payback date of the investment is near and the expected date of obsolescence of the vehicle is far away (mind not only technical aspects, but regulation, acceptance/penetration and financial viability). I wouldn't advise a young professional to drive uber as a full time job though. He might be making enough now, but when/if obsolescence comes, he'd be out of a job and lacking the skills he should be acquiring now.
