I will say, however, that along with probably a lot of others on this forum, I have driven on repaired tires on sedans, vans, and trucks for literally years at highway speeds and never had a problem. Was I just lucky? Maybe so, but I also think that the chances of a catastrophic tire failure on a properly repaired tire are pretty low.
Would I drive a repaired tire at high speed? No, as common sense would dictate that the chance of a failure increases with speed, as does the severity of the outcome.
Tire companies and auto manufacturers err on the side of caution. Why? Maybe I'm just a cynic, but I think it's liability in case of litigation.
