Let's share everything then: PCs, pianos, houses. No, a car is something too personal to be shared. I smoke, the stranger doesn't what happens? Or vice versa. He breaks the car who pays? Legal disputes. I need the car he's using it, what am I to do? It can work for workers from the same office. One car brings 4, it's ok. Other than that, forget about it. Not to mention the economics at play. A whole industry would collapse. If there's something I learned in this life is that money comes before everything else. Trying to save this planet as I watch more and more people install AC in their house is hilarious. Colder for you, hotter for everyone else. And the planet. We'll never save ourselves. There'll be harsh selection. And lastly, if even EVs are a problem I dunno what else to try. Public transport doesn't get everywhere, it never will, so it's not a solution. Oh, and we're not talking about gravity.
