Likely the war chariot gradually went out as horses were gradually bred to be
bigger. I am reminded here of a children's book about ponies that I read:-

Whereabouts in the modern scale of horse sizes and types (pony, hack, charger,
etc) do wild horse skeletons come which died before the wild stock could have
been mixed genetically with escaped domestic horses?
