IMO, the VW is just too expensive. Now, if you're getting the tax credit on the VW, and of course can't get it on a Tesla anymore, that makes the difference. But without the credit, the id4 is virtually the price of an AWD Model Y. For a vehicle that doesn't have AWD, has a ton less power, is significantly slower, less range, and no supercharger access.
Now, those aren't awful hits against a tax-credit-fueled $10k savings (or whatever). But I don't think it's close to there yet.
There are a lot of weird things from the reviews I've seen, too. Spotty voice recognition, "free" charging requires you to use a fiddly phone app, the car only has 2 window switches and requires that you toggle between front and rear with a 3rd button (wtf), and the Nav system is awful and routes you to chargepoint (ultra slow) chargers on a roadtrip, vs DC fast chargers.
So much of this can be changed in software, and maybe VW will drop the price when the tax credits go away, the same way Tesla did.
But, it just seems like far too little car for the money.
