It cant ever happen. The only thing close enough to ever hit him would be a subway running through his basement.
Unlike other elections, you are voting for electors. If Biden drops out or is determined by the DNC to be no longer the real candidate, the electors can vote for someone else. There might be problems with faithless elector laws if he is still alive, but no one has been punished for not voting as directed.
