SpaceX's Telsa will probably not collide with anything for millions of years

In most realizations, the Tesla does not collide with any object over the timescales we considered. Although there were several close encounters with Mars in our simulations, none of them resulted in a physical collision. We find that there is a ≈ 6% chance that the Tesla will collide with Earth and a ≈ 2.5% chance that it will collide with Venus within the next 1 Myr. The collision rate goes down slightly with time. After 3 Myr the probability of a collision with Earth is ≈ 11%. We observed only one collision with the Sun within 3 Myr.
