Maybe if you could only buy/sell at a stoplight, to reduce distracted driving?

It brings to mind a video named "Prius Stealth Camper Build"[0], where the owner has a microwave and fridge powered by the car. Were an Uber driver able to fit all these amenities in their car and still have ample passenger space, it would almost be like a mobile 7-11 - get your breakfast during your ride to work.

Count me out. A few drivers offer some candy or water, and if I take them up on it I tip for that too. I asked once, he figured he was making 3x on tips over the cost of the refreshments.

I'd rather keep doing it that way.

I am not looking forward to getting sold stuff in an uber ride

I wouldn't buy anything from Uber but person to person transactions would be great.

People could just piggy-back their apps on the Uber/Lyft/Grab networks, but outside of them.

What about music a la a mini jukebox?
