The random walk of cars and their collision probabilities with planets • ArXiv
Hanno Rein, Daniel Tamayo, and David Vokrouhlicky:
<p>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.</p>

Well, you did ask.

Where is Elon Musk's Tesla Roadster with Starman? • Where Is Roadster
Ben Pearson (who isn't anything to do with Tesla), using data from Nasa's JPL Horizons:
<p>where is this vehicle? The current location is 2,295,742 miles (3,694,640 km, 0.025 AU) from Earth, moving away from Earth at a speed of 6,732 miles/hour (10,835 km/hour, 3.01 km/s).

The car is 137,198,709 miles (220,799,988 km, 1.476 AU) from Mars, moving toward the planet at a speed of 42,967 miles/hour (69,149 km/hour, 19.21 km/s).</p>

All those numbers are out of date now. Visit again regularly! And note from his graphic that it looks like its closest approach to Mars will be October 2020. Not quite close enough to, er, park though.
