Can't remember title for awful movie Need Help!!

[BadMovieLover]

I remember seeingt this terrible movie about  a guy  whose brother got killed by a  drunk driver and so he becomes a street vigilante and  modifies a chevy pickup  with a  grappling hook mounted on a cannon in the bed  and goes around stopping (with the hook) drunk drivers until the cops can get there and  arrest them.   I  don't know  the title- but it came out  in the late 70s early 80s.  It is stuck in my mind from my childhood.  any help would  be appreciated.  Thanks, Luke

but I'd like to.  That sounds like a decent waste of time.

          It was the 1986 made-for-TV movie "The Gladiator",with "The Soldier"/"Wiseguy" star Ken Wahl as the title hero.It was soon shortly released by New World video afterwards. Nancy Allen,Robert Culp,Linda Throman,and Rick Dees(Mr. "Disco Duck" himself)were the co-stars,and Abel Ferrera is the credited director(accroding to the Psychotronic Movie Video Guide).
            Yeah, B.M.L., I also have searingly burning memories of that movie,just as much as you do,so you're not alone in remembering it.
