Hydrogen cars are just electric cars with a fuel cell instead of a battery. (Unless you're talking hydrogen internal combustion, but that's not the major drive in hydrogen powered vehicles.) The problem with taking a hands-off approach to competing technologies is that it's not a level playing field with the entrenched technologies at all. There are subsidies and externalized costs all the way along the hydrocarbon supply chain.
