If you can’t get enough of it, more details on recent N-body ensemble analysis of the Tesla which suggests it (or the remains thereof) could continue to orbit the Sun for something of the order of ten million years. There will be numerous encounters with Earth with one likely in 2091 with the object passing less than a Moon distance away. There would appear to be around a 6% chance of the Tesla impacting Earth within the first million years, growing to 10% within 3 million years (with a 3% chance of impact with Venus and virtually no chance of impact with Mars).

arXiv:1802.04718v1The random walk of cars and their collision probabilities with planets
On February 6th, 2018 SpaceX launched a Tesla Roadster on a Mars crossing orbit. We perform N-body simulations to determine the fate of the object over the next several million years, under the relevant perturbations acting on the orbit. The orbital evolution is initially dominated by close encounters with the Earth. The first close encounter with the Earth will occur in 2091. The repeated encounters lead to a random walk that eventually causes close encounters with other terrestrial planets and the Sun. Long-term integrations become highly sensitive to the initial conditions after several such close encounters. By running a large ensemble of simulations with slightly perturbed initial conditions, we estimate the probability of a collision with Earth and Venus over the next one million years to be 6% and 2.5%, respectively. We estimate the dynamical lifetime of the Tesla to be a few tens of millions of years.
