Depends on what you mean by "small scales". Relativity works to the length scales accessible by accelerators (1 TeV, or something like 1e-18M - and probably extrapolated a lot further). There are issues with quantum gravity but they only become significant at energy scales approaching plank energy - far beyond any conceivable technology. There are also possible issues with relativity at cosmological scales.
The problem is that relativity seems completely under all technologically reachable conditions. Star drives just don't seem possible.
We *could* be missing something, but it is very difficult to imagine a set of rules that allow FTL or other fun stuff, but which would not have been noticed in present day measurements that range for accelerator scales to cosmological scales.
