IMHO quality jackstands are very safe when used correctly, and I'd bet the user is to blame for nearly every related incident.
Having almost lost an uncle to a car that fell onto him off of mis-used blocks, I'm very thorough about making certain a vehicle is properly supported and completely stable before working underneath one. That said, I think it's only natural to feel uncomfortable under there, and I always find myself whispering a prayer that a 'quake doesn't hit at the wrong moment.

Tell me about the "Quake Prayer"....I live in southern California !
I think about it EVERY time.....
Be VERY careful jacking the car by the front crossmember. They can be dented.....
Most crossmembers are already dented . I worked as a mechanic in the 70s and we always used the crossmember in the front and the rear axle in the rear . No one cared back then .
For long periods of time and for simple better support of the nose I put stands under the sway bar bushings or under the lower control arm spring pockets. Depends where I have to work under the car.
I dont like leaving a big block hanging out over the frame with only the stands at the number 2 frame mount. Just too much beef hanging out in space.
I support my cars way off the ground up high. I support the vet at each end of the frame on the jack points and under the engine cross member in the front.
I also put several other jack stand under the car, not supporting the car but set up to but not touching the car, as close as I can get them.
I read the newspaper daily and every few years there is an article about some local person crushed by a car falling on them. Jack stand can be purchased very cheaply from the major chain stores and moved around easily when not supporting the car. Why not put several under the car and be safe.
I know some will say this is overkill, but I agree with the above. I always put a pair of jacks at the ends of each side rail or 4 times 2 or 8 jacks total. Also put a couple more jacks in the front to help support the front end too. My logic is the downside risk is big and jacks are cheap. Also make sure your jacks on each corner are holding up weight and are not a "soft foot" or not holding up any weight. Nothing is more exciting than accidentally bumping one of the single corner jacks out that is actually not holding any weight up and realizing the car is then up in the air on only the other 3 corners.
I don't even fully trust jackstands - especially since most are made in China. I place a tire/wheel under the frame for added comfort sometimes - just in case.
That's exactly what i always do, most times when i have the car in the air i'm doing suspension work anyway so i "stash" the tires/wheels under the frame somewhere. Give me a little more comfort knowing that if something fails, also if my son or one of his friends leans on the car at least there's 8" or so that i won't crush me. lol
