Only 2 car chase scenes ever worthwhile; here just lengthy filler

I could have twice left the theater for long periods without missing any plot while they do all this car chasing, crashing into other cars for like 30 minutes at a stretch, all stupid and meaningless and unrealistic. I've concluded that directors who fill up a movie with these are wasting our time and a lot of metal -- and insulting the viewers' intelligence.

The only car scenes that were not a waste of time and metal, in my opinion and from what I've scene, are Bullett (the mother of car chases) and French Connection (car chase to another dimension). Otherwise -- please directors, develop enough of a plot that you don't need these stupid fillers.
