  Shooting through a windshield is a very dicey proposition. There is an amazing amount of glare that you don't see when you are in the car, but which you will see when you look at your camera footage. A far better solution would be to mount a GoPro (or some other small, disposable camera) on the exterior.
  
  Nevertheless, if you insist on using a DSLR, then only with a wide-angle lens will you get "the surrounding areas" to give context to your road.

  For shutter speed, you don't want too much blur. 25 miles per hour is 36.7 feet per second. Since you are shooting at max 45 degrees, 36.7 \* cos(45) = 26 feet per second. If you shoot at 60 fps with a 180 degree shutter (1/120th of a second), then the largest blur on the sides will be 26/60 = 2.5 inches. 2.5" may be an acceptable amount of blur for a building-sized object that's on the way out of the frame.
