Because right now we don’t have that much excess energy… Therefore it’s just a waste of energy to use it, because it is way less efficient. AND on top of it an hydrogen car also needs a battery just a smaller one. So it has all the downsides without any upsides. The only upside is that you can recharge your car faster and it has some more range. But both those things don’t matter for the average consumer

We need to stop using animals. Not extend it. I mean I really don’t get what’s so hard about testing if a product works on humans in the real scenario.

Why kill animals? It’s not like menstrual products don’t work. just keep buying the stuff that works more than others if the little difference between the testing fluids and blood are really existent.

And it’s not like the products would be better with blood testing. That’s not how capitalism works. It needs to work good enough to be bought with the biggest profit margin possible. So using blood for testing just creates suffering for animals for no reason other than you can put “tested with animal blood” on the box. I wouldn’t see that as a plus
