- First of all, there is no natural gas fuel standard
- Safety, there are no safety standards. If there were, tanks often used in other places, such an upgraded would be more expensive
- Rolling out refueling over the whole of the US/Europe would be difficult. Most places in Europe don't have these cars.
A better and safer alternative to natural gas would be methanol. And because of the US ethanol policy, the US already has a surprising amount of Flex Fuel Vehicles.
If you could have a bunch of fuel standards for ethanol/methanol and a vehicle standard for those fuels, depending on the price, people could buy different mixes.
Converting gas to methanol is fairly efficient and can be done directly at gas production sites, sometimes with gas that would be vented instead. But there isn't a big market for methanol right now.
In China such standards do exist M20 and so on. However sadly there methanol vehicles usually use methanol made by coal.
The US would have had much lower fuel cost if they had a strategy of methanol and ethanol at the same time, and require all vehicle to be FFV. Standardizing M20/E20, M50/E50 fuels for example.
However all of this is now no longer very useful as car market is rapidly switching to electric.
For some trucks using generated fuel might be useful. Dimethyl ether would be great for long range trucks and ships rather then hydrogen.
