I think that would require some working time for Scawen to have a fully working safety car. The current AI's top speed is maybe fast enough to play the safety car's role (!), but there would be probably some "when to come on the track and when to go off the track" issues.
First, it would be totally ridiculous, as most races that aren't league races would be red flagged after the first corner. Besides, assuming the first corner is passed through correctly, there's probably enough SC causing crashes in that kind of races to cause a SC per lap, which is ridiculous. So we're definitely talking about a league race only option here, and that's a lot of time from Scawen to work on a feature that, while very interesting, would be scarcely used.
Not only there's the AI issue, but a working safety car would mean some safety car lights, and the current engine as it is doesn't do that very well (or not at all considering 'lit lights' are really just 'lit textures').
