That’s fine, and while I don’t think it’s as bad a thing as you do, that’s a reasonable position. But that issue is entirely separate from whether or not same-day delivery will cause traffic problems.
It’s disingenuous to claim that same day delivery causes traffic problems because you dislike the other effects of it.
In any reasonably dense urban region (which is where Amazon is actually rolling out same-day delivery), the volume is high enough that orders can be combined. The few next-day packages I’ve gotten from Amazon were delivered by vehicles carrying multiple packages.
Plus, even if it’s not combined, it’s still no worse than me going to get it. If I order one thing for next-day, then that’s replacing one trip to the store that day with one trip by a courier. No additional traffic.
I think you misunderstand my point. I do that too. As I joked at the end of my post, I’m not ordering diapers for next-day delivery. I already know in advance that I need to buy diapers. But I did, for example, buy a replacement router with one-day delivery a few months ago. Because my router died and I needed a new one.
And, also: I’m a planner, as apparently are you. Many people are not. It’s all well and good to say that people should plan their purchases, but many don’t. They end up driving to the store quite often. Same-day delivery should be judged against people’s actual behavior, not their hypothetical best behavior. If everyone planned well enough to do all their shopping efficiently in one trip per week or two, then the benefits of same-day delivery would be much lower. But they don’t.
20 minutes isn’t really that long. It takes me, absolute best case scenario, about 5 minutes to put my shoes on, walk to the garage, pull the car out, turn around, drive to the store, park, walk to the store, and another 5 to do the same in reverse. That gives 10 minutes to find the thing I need and buy it. So, the best case for me personally is probably around 12 minutes if I know where the thing is, or find a helpful employee quickly, and I don’t have to wait long to buy things.
But that’s if the thing I need is sold at the closest grocery store. If I have to go to a pharmacy, the one-way trip is up to around 7 minutes. Auto parts are also about 7 minutes, and electronics for remotely reasonable prices is about 12 minutes away.
And it also assumes that I don’t have to wait in line, that I either called ahead to make sure they had the thing or just hoped they’d have it in stock.
Yes, I could go on the way home from work (sometimes, it depends on the store). But then I’m doing my shopping at 5:45 or so on a weeknight. In my experience, that is when stores are the busiest, so while I save a bit on transit time, I spend more waiting in line.
Compare to the maybe three minutes it takes me to pull my phone out, search for the thing, and click buy. This is not a hard call.
It was? Is there reason to believe that people are getting the mass of purchases delivered same-day?
