Not practical to have zero cars. Residential areas aren’t set up for it. How you going to get your shopping in with 2 kids when it’s pissing of rain like it is 70% of the time here in Scotland.
Priority should be public transport with cheap public autonomous taxis that can drive 24/7 and unclutter the streets.
I don't think you'll find anyone with a lick of sense in here that's advocating for zero cars -- just that the way the system is currently set up prioritizes cars above everything else when it ought to be the other way around -- cars ought to be the very last resort instead of the first option most people go for. Taxis absolutely have their uses, and yes they should be cheap, but not so abundant as to divert people from using mass transit like buses or trams
Most of America's suburbs are designed to have a supermarket somewhere on the outside of the zigzagging streets of the residential homes. Golf carts would be perfect, in the vast existing suburbia. Legalize golf carts for slow streets in the burbs, and you'd get a massive reduction in car use. A quick electrification of vehicles.
I like bikes, I get it that many people don't. But at the very least legalize golf carts on slow streets. I feel that the average suburban home wouldn't mind getting a golf cart as a second vehicle. It's a quick way of hopping to the strip mall to get milk, or a morning coffee.
I have an electric car,but I also have an ebike(recently got it, maybe a month ago). I generally try to do small shopping trips on the bike,which is a lot of my shopping atm, but sometimes I need to transport stuff that just couldn't fit (cat litter, 40lb bird seed, stuff like that). I also have a more than 40 mile trek for work, so that isn't feasible on the bike. While I do get to work from home a lot, every other week I need to be in office for 3 days.
Having the electric is at least better for that, and my electric wasn't a luxury car like the OP states, it's a 2015 leaf that's down to 20% or so when I get to work, plus there aren't a lot of compatible fast chargers around for it. Even slower j1772 types seem to be not working half the time... I dislike the direction of bigger SUV and crossover eCars that seem to be the trend nowadays and I don't want to go back to ICE, but feeling some limits.
