I like the convenience too. It’s almost “back to the roots” to the times when your local grocer/trader would deliver the goods to the local citizens, since he was the one with the car, though today this dude is replaced by a faceless webshop. And even though this option includes cars, it reduces the number on the road, since one delivery vehicle will (potentially, though not necessarily) replace one car for every household it’s delivering to. This vehicle (theoretically, at least) drives the most time/fuel-efficient route, instead of every household driving to the store(s) and back again. Funny how this is moving traffic of the roads and turning it into digital internet traffic!
