You're right about the prices. Consumers claim range is an issue, but a typical daily commute is under 20 miles one way. Most households have multiple vehicles, so keep your ICE SUV for weekend road trips. I'm not saying range isn't a selling point, because it absolutely is. But as a practical matter, anything close to 250 miles real world is more than enough for the vast majority of use cases. My understanding is that 150 kW charging is quite good, and the fastest options are already excellent (and will be mainstream in 7 years). Unfortunately I believe the BIF intends to subsidize the installation of a lot of slow L2 chargers, which are arguably already obsolete.That is a big one. Range would be far less of an issue if there were as many charging stations as gas stations. Secondly, cutting charging times down. Lastly, getting prices down (excluding the land barge problem @Brainonska511 mentioned). I hope to by a BEV in a couple years when it's time to send off my Camry to it's likely last owner.
Unfortunately, growing the EV market 'organically' just won't work and China was the first to recognize this. Straight out subsidies at POS (!tax rebates) would help, as would raising the price limit. If we want to switch over to selling almost exclusively BEV in 20 years, we will have to spend more than the $83B allocated by the Biden Admin and Congress. Changing out and entirely ICE/Fossil Fuel based transport economy is a pretty heavy lift. The very large auto Industry as a whole and consumer momentum argue against any organic growth (particularly on the consumer side based on savings in the first 7-8 years the first owner keeps the car).
China is already up to 25% BEV market share of new auto sales (nearly 40% "plugin" market share). They have tons of organic growth, because they have tons of affordable models to choose from. So China is a bit ahead of California, way ahead of the U.S. as a whole, and on pace to replicate what Norway has already done. The EU is very concerned that Chinese BEV automakers will dominate their markets and if that comes to pass, the U.S. could be next (trade war notwithstanding).
Subsidies certainly accelerate the transition, but I mainly disagree with U.S. BEV subsidies as currently constructed. Initially they were designed to aid automakers willing to develop BEVs at a time when there was no market for them. So setting a lifetime manufacturer cap makes a lot of sense to me (probably 200k is too low). Now we've dropped the cap even though Tesla dominates sales, so what ends up happening is that we're all subsidizing the upper middle class purchase of $50k+ BEVs. If your only goal is electrification as quickly as possible, then that's okay. Otherwise it's an inefficient use of funds (notice that there's a massive FY2023 federal deficit and debt servicing costs are growing briskly), and essentially a wealth transfer from all taxpayers to the top 15% of car buyers (my ballpark estimate).
Sure it's a Scandinavian country of barely 5.5M residents, but Norway has proven that it doesn't take 20 years to transition if your consumers appreciate that BEVs are a part of the solution to reducing carbon emissions (and public policy is aligned with this goal). Now if your consumers are addicted to light trucks and inefficient ICE drivetrains and are being told BEVs are evil, then it's anybody's guess how long it'll take us. When there's near price parity between BEV and ICE, and similar options as far as models consumers want, then we can truly judge consumer demand.
