I recall eight to 10 years ago when Domino's did a gag type of advertisement of a drone delivering a pizza. That gag is turning into reality, see
UPS uses drone to deliver prescription drugs.
Don't be thinking that you are going to be able to make a career out of Grubhub deliveries. I also don't recommend any career planning with being a long-haul truck driver or taxi driver for that matter. Technology will be a job killer for these types of positions.
