CNG & LPG only works for somethings & not the general public.
LPG vehicles for the public already happens in EU & some other countries around the world & FailArmy et al shows only the tip of problems including car explosions. Very popular in UK & others to convert many old ICE cars because of lower taxes.
Both has been use for Fleet Operations for Decades & vehicles roost @ night @ same location & refilled w/ CNG overnight.
Refilling CNG overnight slowly stops heat buildup that fiber wound tanks in the vehicles hates.
Because CNG need local Compressors even when have high pressure NG to the compressor to boost even higher to fill the vehicle.
LPG for vehicles require permanent tanks in them too. Not like Forklift etc that use portable tanks.
Both need Tanks re-certified or replaced at 10 years max to meet U.S. DOT rules same as most other tanks. Other countries have similar rules. Many Fiber tanks must be replace @ 10 years. Alloy & steel can be re-certified @ 10 years but they have limited life too.
Part of getting Certs/License to run Forlklifts etc is how to deal w/ whatever Fuel or Battery to run then. Even then many Companies only allow Maintenance to handle refueling/recharging these things to keep number of people very limited.
Side Note: Many Used LPG, Scott Packs & more sold in 2nd hand markets have expired tanks and need replaced or re-certified before use actually use them. Most refilling companies will not service an expired tank. All tanks have a Date somewhere on them. Example: On common LPG for the grill in stamped on the handle/guard part near 1 end.
Even w/ USDOT requiring Overfill preventing valves on portable LPG tanks for Grills etc... (Believe is 5 to 40 lb LPG even tho most only see 20lb tanks) They still Explode because General Public still does same thing w/ crap hoses & more connected to them & leaking to exploding. You don't hear about this because big MSM don't cover this & even local News only barely mentions this often only when someone in killed.

I absolutely positively hated refilling forklift LNG tanks. The cold, the pressure, the flammability. .. the uncertainty.
But, I also hated refilling the tank on an old butane tractor my uncle had back in the 60s.
(he was later killed by it, when he refueled it with the engine still running. No explosion, just a flash over fire that burned him badly because even tho ya don't know it, if there is a leak, the gas permeates your clothing and even underneath your clothing. He did not die instantly but died a few days later from infection)
Hated as well, the LNG oil field drilling rig engines. Waukesha mostly. They stunk and it was more than a little un-nerving to look at them at night and see the sparks running up and down the spark plug wires from salt build up on them. It was not at all unusual either, to see a little blue flame somewhere a gas line leaked just a bit.
Usually just blew it out or put a gloved hand over it to smother the flame so it didn't catch the engine on fire but it would pop back up sometimes.
(These usually ran straight off wellhead gas, not commercial natural gas. It was not treated gas..this had no artificial odor added -mercaptan)
(First thing the crews had to do, was run up to a mile or more of aluminum gas line, from the nearest producing well up to the new drill location, into a pressure regulator and then to every engine on the rig.)
Some of that welhead gas smelled worse than LNG or LPG. It sometimes had a bit of H²S in it.
Fun times.....
I was so glad when the last of those engines was gone and everything ran on diesel.

Battery swap stations are a bad idea. The concept has its merits until one considers what a bad actor could do. Such bad actors have all the time in the world or pull the battery pack, tinker with it, steal parts off of it or even sabotage it.

Don't need "bad actors" making problems. You & others missing that when you have a fire.... Now you have a 3rd party handling the battery. So who to sue by people hurt etc after Thermal Runaway happens? Worse happens in a Public Garage, in a Tunnel, etc.
Car maker blames Battery company & other way around can make a lawsuit last for decades more & often already last many years now.
This alone gives many people nightmares.
Even Car & other Insurance have more reasons to raise prices w/ swap-able battery setups. Their already doing that w/ EV now because they Total even "minor" wrecks that normally fix but any damage to the battery = no fix.

OK, you've convinced me my "Idea" is not worthy of serious consideration. I'll go back to working on that nitrogen powered vehicle idea...................

Yeah, its a shame when you hear about some tech and then remember that way too many humans are poop and it would never world in actual society...
Every time I read the term "Bad actor" I literally think of a bad actor...like a movie actor...

That seems like "weak tea."
If you were at an outdoors concert or some other outdoors event, and wanted to use a Porta-Potty, would you worry that a "Bad Actor" might have rigged it to explode if you opened the door to use it?
That's about the equivalent of this strange remark from Doug85GT about battery swap stations.
What say you?

Is that a promise we can hold you to? Maybe I'll start taking the train..........

I say you haven't been around much..
I'm guessing you've never seen ports-potties turned over at a county fair with some unknown and unsuspecting person inside it.
Or a tailgate off a new truck missing because some dopehead bad actor was stealing them to sell for drugs.
Or been without power because some bad actor took a high velocity rifle to a sub station transformer just to cause havoc.
Or went to start your vehiicle and heard a very loud exhaust tone because some bad actor crawled under it with a battery powered sawzall and cut the catalyic convertor off while you were in the grocery store.
Or woke up one morning and saw every tire on every car in your block slashed by some bad actor just for kicks and giggles.
Or a thousand other things that bad actors do every single day in this country either for profit or just because.
Get Greta's pigtails untied from around your gonads and look at the real world and maybe, just maybe, you'll 'get a clue'
