I don't think there is a minimum. You can set it to 1, updating 1000 times a second.
Of course the more updates the bigger the "lags", but minor tasks like speed calculation won't slow your server down by a noticable amount. So 200-300ms should be fine I think, unless you have 1000 players in your server all driving in a vehicle simultaneously.
