Anyone care to comment on this statement about Toyota engines?

Toyota engines can't blow when the belt fails.
I'd find it very hard to believe that Toyota make non-interference designs these days.
Some older designs are ok if the belt goes, like early (1990/1/2ish) v8 lexus is ok but later isn't.
Most belt drive OHC as a general rule are not OK.
At a guess of the belts that bereak 99% fail because of poor maintenance. The rest are related-item failure, such as water pump or idle wheels, and very rarely stones and mud getting in the belt area.

Blimey I must have been dreaming whem my Corolla broke it's belt, taking out
6 valves in the process.It was somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Dave Plowman (News)" saying something like:
How I wish it could be true, since I've just bought an old Toyota estate and need to change the belt, but I think IMM is talking out of his arse (again).
Just had my timing belt let go and bend the valves after having had it changed at an independant garage as I'm not longer able to do it myself. Too old and stiff!
It appears that they did not locate the tensioner correctly on its locating spigot and the holding bolt eventually worked loose with the usual consequences.
Another independant checked it and the original garage repaired it FOC although managed to leave it with a substantial oil leak which I've since cured, just poor quality workmanship.
BTW isn't the MR2 non-interfernce?
