The blue Tacoma in the front is a Double Cab (other automakers call this model a Crew Cab). Double Cabs have full rear seating and full rear doors that open towards the front of the truck--just like normal front doors do.
The red Tacoma in the background is an Access Cab. It has rear doors that open 80-degrees for entry and exit from rear seats. Here's a closer look at rear seating in a 2006 Tacoma Access Cab.
