Cars should come equipped with the vehicular equivalent of a PLB. Something like OnStar, but not totally reliant on cellular service (It should be something that can take advantage of both cell lines and communication satellites).

I expect to see "black box" data and GPS loggers with crash activated cell/EPIRB, and perhaps video, someday in the not too distant future, followed soon thereafter with a logged data reader in every patrol car. A mixed blessing, at best.
