You forgot to mention that the point of the Toyota deal is that while they can put their racing cars in the games, the road car however have significant restrictions, namely the game cannot use custom body / exterior parts (aka no bodykit, no wings, no custom bumper, etc).PC2 also has Toyota road cars as well, the GT86 in two road car variants.
AC also has a good number of Toyota road cars.
However, both of these were released before the suspected exclusivity deal.
Big name publishers like EA (NFS), Turn 10 (Forza), and Ubisoft (The Crew 2) refuses to oblige to it and instead just omit their cars altogether. PCars 2, Asseto Corsa, GTSport do have quite lot of Toyota road cars but remember in that they all didn't feature body part customizations.
Nevertheless, it's still sucks for the players in the end.
