Which, taking a step back, if franky ridiculous.
Why not use a battery and the planet-wide instant power delivery system we built and are using for most of everything else?
Imagine we were operating with 100% EVs today, would people be advocating for adding in gasoline tech as hybrids?
It is obviously ridiculously over the top, but I think it paints interesting analogy.
I feel like the population that both drives very long distances regularly and is willing to spend a large chunk of money of make the trip a little faster is pretty small. Plus it would be pretty hard to find gas stations if most people drove EVs.
If you don't have a long range battery, you might have to stop every 60-80 minutes of driving to charge. That will get annoying pretty quickly, especially since it's not like a smaller battery takes all that much less time to charge.
So I would expect the long range battery market to be quite big, and a range extender would have a good chance at grabbing many of those users.
Even if gas stations are somewhat uncommon, you'd only need to find one every 200-300 miles, and the worst case scenario is just that you go back to pure electric mode. You could also fill up a 5 gallon can for another huge chunk of extender range.
A single tank could save you an hour of waiting to charge.
To get "gas ranger extender" you still need oil drills, tankers, pipelines, refineries, tanker trucks, gas stations.
Without gas cars, we can retire all that infrastructure.
Well, we can obviously reduce it if we reduce gasoline consumption from the status quo (true with moving to hybrids, especially plugins using gas mostly for range extension), but since its not used exclusively for autos, we can't retire it even if we replace all autos and do nothing else.
BMW charged $4,000 for the Range Extender option in the i3, at that price, the manufacturer may as well just put in a bigger battery.
The range extender only adds around 70 miles of range:
current 2018 EPA estimates ding the more powerful i3s from 114 to 107 miles. BMW hasn’t cited an estimate for the REX model, which currently stands at 180 miles with the help of a 647-cc twin-cylinder engine.
They could put in a more powerful motor than that small scooter motor, but then that costs and weighs more, and then the car becomes a plug-in hybrid rather than a battery electric car with range extender.
And there seems to be low demand for plug-in hybrids as there aren't many options.
When I bought my Honda Accord Hybrid, I looked at the Clarity plug-in hybrid but decided against it. It didn't drive as nice as the Accord, cost nearly $5000 more, plus I was doing some regular long distance travel at the time, the accord has a ~500 mile range, the clarity has a ~340 gas+electric range, though the plug-in range would cover my commute.
And the Clarity was rated 40mpg highway, while I get around 50mpg @ 60-65mph with the Accord Hybrid (drops down to 44mpg at 70-75mph)
It's funny how HN'ers will fight to the death arguing for swappable batteries in cell phones, where they offer vanishingly few benefits, and against swappable batteries in motor vehicles, where they could potentially make all the difference in the world.
Nobody with a new battery is going to want to swap it out for a old, potentially degraded battery. But everyone with an old battery would be happy to try to swap their way into a new battery.
Instead, I think you'd need a model where the battery isn't included in the price of the car, and you have a monthly subscription to rent a battery from either the dealer or a third-party. That way you aren't attached to the specific battery you're using, and the subscription fees go towards replacing old batteries as needed. The subscription would either be a base fee + price per replacement, or a base fee for rental + unlimited replacements.
Great, this old schtick again. News flash: nobody cares whether or not they own their car battery. With modern BMS systems, you would basically pay by the coulomb.
But yeah, I think this particular ship has sailed, at least for the near-term future. Huge missed opportunity. Refueling an EV should be as quick and easy as swapping out a BBQ propane cylinder -- which is also something you don't care if you own or not -- at your local convenience store.
Perhaps in the future, total swap automation and inexpensive battery restoration or transport will reduce the risk of building the network and EV sales will finally become viable for the small minority who don’t want to take periodic breaks during the occasional long trip.
As far as “no range anxiety” people in that world would just be making similar arguments, “what if there’s no nearby gas station”, “what if it’s out of gas”, “I can’t just plug-in anywhere” etc.
Today with EVs and modern battery tech that isn’t true.
Then swap out gasoline for diesel. If nothing else, I can get vegetable oil at the grocery store at a price that isn't too bad.

That's not how (plug-in, and surely these would be plug-in) hybrids work...
Somebody will find something to do with the unused byproduct gasoline. I consider filling up my car to be a noble use instead of just burning it.
