Despite the title not understanding what a lightyear actually means, good. We need fewer cars and especially not ones that have shown they will just run people over without care.

Not to mention cars steal resources from other countries, whether it be oil or metal for batteries etc. What we need is more publically funded transport that actually works well and is quick, safe and even rich people/politicans would travel on.

One of the worst things ever invented to a degree was cars especially since they often install roadways to completely bypass small 'out of the way' places or worse make cities completely designed around them since there are no places to walk, play or hang out (that's a slight aside but I do think the death of third places has cars partially to blame).

We also need for transport companies to start recycling and actually start caring about their own waste management.

Also, don't make me laugh that it's Elon that is 'lightyears' away from self driving cars, it's Tesla and all the people who actually do the work, Elon is an mediocre man who gets worshiped way too much for having too much money, spending it irresponsibly, acting irresponsibly and then taking all the credit for other's hard work, just like every other billionaire out there.
