Already many of automakers are staring to put their own money into hydrogen pipelines like they are in Germany and hydrogen gas stations like they are in Japan & S.Korea. As they collectively put up their own money for hydrogen stations along with private hydrogen companies and gov't subsidies, their financially viability increases.
Added to this is another major sector that is starting to invest in hydrogen infrastructure is, wait for it, oil companies. Think about it. If everyone started going EV {assuming the automakers can eventually make money off them before going bankrupt}, the oil companies are going to find themselves in the position of trying to sell a product that few actually want and if they shift to battery recharging they are in competition with people who can recharge at home or go to their nearest bank or mall. This would be akin to a gas station today trying to make a living off of only selling diesel........good luck with that.
Oil companies are not going to gleefully look at how their industry is heading for oblivion. They need something to sell to stop the carnage and the automakers need something they can sell that doesn't lead to bankruptcy and by combining their sizeable resources into hydrogen infrastructure, they greatly lessening the chances of death in their respective industries.

A Toyota Mirai hydrogen car costs about the same to buy as a Tesla Model Y Long Range. It costs Toyota much more to build it - Ford's loss on their EVs is nothing compared to Toyota's subsidy of the Mirai, (with its expensive carbon fibre pressurized fuel tank, a fuel cell stack, a lithium ion battery and electric motor).
In BC, it costs exactly four times the price per km to buy hydrogen for a Toyota Mirai, compared to the cost of electricity to charge a Tesla per km. (It's slightly cheaper to drive a Mirai per km than an equivalent priced Toyota Venza hybrid).
As you note, infrastructure is 'limited' - there are three filling stations in Vancouver (except the one in North Vancouver is broken), one in Victoria and one in Kelowna. There are over 40 in California, but none in Washington, or Oregon, so forget the road trip.
Tesla sold $23.9bn of electric vehicles in the US in 2021, and $40.6bn in 2022.
Toyota sold $1.5m of hydrogen vehicles in the US in 2021, and $1.2m in 2022. (Sales dropped from 2,629 to 2,094).
Looks like Hydrogen for cars has a bit of a steep hill to climb...
