It costs money, I guess that's the problem.
This is my guest. ISC, NASCAR, everyone involved is all about safety...but at a price. It does cost money to install them, probably quite a bit so they just do what they think is necessary. But the Hobbs quote is a common expression I've heard for awhile. NASCAR has even seen this over the last few seasons. It seems like we have this conversation every year because a driver has hit an inside wall or some obscure corner where there is no barrier. If they don't install the barriers on all inside barriers at all tracks now, then I really dread what has to happen for them to see it as a necessity.
