Hubble is one of the few telescopes that could possibly image Starman, as a dot. James Webb will have far more sensitivity. It's a really small space rock in a really big space. You can take a look at https://www.whereisroadster.com/ which has information on how big of a telescope it would take to see it, and to resolve it, updated in realtime. The answer ...

The angular resolution of the Hubble and James Webb telescopes are about the same - both are around $0.05$ to $0.1$ arc seconds or about $4 \times 10^{-7}$ radians. If we express the angle $\theta$ in radians then the distance subtended by that angle at a distance $r$ is just $r\theta$. Starman is about fifty million kilometres away, and at that range $4 \...
