The site is actually plenty large enough to not use the taxiways at all, and still make a 40+ second course. My guess is that National will not approve another course that uses the taxiways.

The problem with them is they are narrow and have a significant crown.

Due to the narrow width, there is little to do but slalom to reduce speeds, and slaloms are extrmely upsetting to cars. When combined with the off-camberness of the crown they can cause small mistakes to turn into high speed course exits in fairly random directions as we have seen.

IMHO the only way to continue to use that site safely is to stop using the taxiways, which is not likely to go over well with the general membership of the two regions.

You could continue to push wokkers further off the side, but that dosn't fix the problem, and the next incident may well be a roll over that could involve the loss of limbs due to open windows or worse...
