33million miles to mars from earth and this car is headed for an asteroid belt which contains more than a million asteroids more than 1 km across.. I don’t think this car is going to be your main issue, when you get your shiny new spaceship.
Every atom of that car would have come from space, and space is infinitely hospitable to life, the problem with pollution on our plannet is the affect it has on the life that’s hear.
You could make a similar argument, that there you hurtling through space on your little blue plannet when crash*bang*wallop a 100km wide meteor crashes into you. Now that’s an issue!
If only we had some sort of rocket we could use to defend our selves from such and event, or just stick to living in caves and keep our fingers crossed.
If it’s such an issue then give up your car right now and take to walking everywhere, as a 2 minute drive up the road to buy milk will have a bigger impact on our planet than that Tesla will have on the whole of space.
