You must be kidding...i3 an alternative to Tesla 3? I won't say anything about the looks but just considering the range should tell you there is no comparison.
For families with children, an electric car plus a minivan is a combination that's pretty hard to beat. You get an efficient electric car for commuting, and a comfortable large car for weekend trips, hauling the kids around, and buying a bunch of crap at Costco and Home Depot.
And ordering (and waiting months for) a car is the norm in Europe. I actually think the buy-something-off-the-lot culture is why we get so few options on cars in the US; just a bunch of shades of dull with dull options bundles.
There's a bit of legal stuff behind it too; my understanding is that you CANNOT be legally held to buy a car that you haven't seen (which, of course, seems like an obviously good thing). But a side effect is that if you order your Porsche in pink with purple polka dots and no stereo, then decide you don't want it when it arrives, the dealer may end up with a car that is not so easy to sell.
