Entertainment! is a great record. However, I'm going to just list my personal road trip albums instead of necessarily trying to match your taste.
Electric Warrior - T. Rex
Link Wray - Link Wray
Dixie Chicken and/or Waiting for Columbus - Little Feat
Marquee Moon - Television
Graceland - Paul Simon
The Joshua Tree - U2
The Stone Roses - The Stone Roses
A Northern Soul - The Verve
Blind Melon - Blind Melon
Daisies of the Galaxy - Eels
Polygondwanaland and/or Butterfly 3000- King Gizzard & The Lizard Wizard (depends on if I want moodier psych/prog or upbeat synth)
I also try to throw a records from or about the area I'm driving through. Grand Funk Railroad's Closer to Home sounds better if you can see Lake Michigan, and I'm absolutely playing Sufjan Stevens' Illinoise in Illinois.
