Well when it first came out but I don't remember there being that many cliffracers..
Oh man.
You have no idea until you decide to trek around the Molag Amur/Red Mountain for a while attracting the attention of every cliff racer that spawns without stopping to kill any of them while at a high level or with tgm on.
And I'll do the "make Tamriel's NPC count look 'realistic'" trick by multiplying the average number of cliff racers encountered in a single Molage Amur/Red Mountain exploration session by something like 100
2, just to further prove just how many of the buggers would actually be out there.
