Somewhat dismissive but this comment deserves at least one earnest reply.
The culture hasn't caught up with the power and availability of electric cargo bikes. Carrying four bags of groceries two or four miles is trivial in good weather, practical in a lot of poor weather, and you can probably manage six, you can hitch a trailer and go to CostCo if there's a safe path for that.
Anyone can do that if they don't have severe hip immobility, because you pedal when you want to, not when you want to move. It's great for the cold but not deep winter parts of the year: you start moving with the throttle, and pedal to warm up, you can stop before you start sweating into your jacket. In summer, you can work up a sweat, or enjoy 20kmh breeze and just cruise.
They cost a few grand, can come with an eighty mile range, and handle realistic traffic speeds safely. Once the public consciousness notices these things, you'll see a lot more of them.
Edit: I said "a few" grand but there are a couple compelling bikes which come in under 2K.
