Those are mostly all wrong. And indeed they didn't shelve the idea, the companies that have had hydrogen cars on the road for years and years have had great success with it; they just haven't pushed to build infrastructure, because the needs the different storage devices vary widely and it is still unclear which technologies will be most competitive.
3 is especially funny. Better go tell all those BWM owners their cars start slower than a hand crank... they'll probably laugh at you while turning the key to "on" and driving away.
Hyundai actually has a mass-produced hydrogen fuel cell car (well, SUV) now, and Europe is building out limited infrastructure. Even people who want to build the infrastructure are slightly hesitant because everybody is worried that new technology will be ready "soon" that will make them look silly with the old tech. But the build-out is starting anyways.
The European infrastructure project is being supported on the automaker side by BMW, Daimler, Honda, Hyundai and Toyota, and on the hydrogen supply side by Air Products, Copenhagen Hydrogen Network, ITM Power, Linde and OMV.
That is actually all news from last spring, kids.
