The four jackstands always left me feeling very secure. That is until I moved to California. Now after 15 years in sunny southern CA, I am uneasy when ever I work under a car, because you never know when the ground is gonna shake, sometimes mild, sometimes not. And if that movement will collapse building and overpasses, it surely will collapse, or knock over jackstands. Now I work very quick and with as little of me under the car as possible.
