Used to do this in Belgium. Still less convenient than driving, and kinda annoying to use during a Canadian winter.

And again, more limited space.

I commute by walking (1h per day) and typically avoid the car when possible, but for groceries there’s just no way I’d go back to walking to and fro.

For those to be effective, you do need good walking infrastructure.

I'd grab one of those except for the fact that I don't have a sidewalk connecting me to the grocery store. Totes end up working better for me as a result.
