I do obviously love all three of the scenes mentioned above... but to me the mine cart chase in "Temple of Doom" is far superior to the other two. It's totally thrilling, incredibly fast paced and the scenography is absolutely fantastic!!
I think Spielberg has outdid himself with the direction of that scene. The shots are perfect, they let the action flow so smoothly that you simply can't get captured... and they also (excellently) manage to give extra size to the spectacular scenery surrounding the mine carts!!!
Regarding the truck chase in "Raiders"... I don't like it as much as the others... the stunts are epic and there are a couple of brilliant brainwaves (when Indy and the german soldier share a smile after they crashed into that sort of building site... and then Indy just punches the soldier in the face...
LOL... total genius!!) but the general impression is that the scene runs TOO SLOW... don't know, it can't impress me very much... but great music, that's for sure!!
