No, tanks don't explode. Within their rated standard they are very safe. At worst if they do fail it is "gracefully" from rust and end up with a small leak - often in the form of pinhole corrosion, due to condensed moisture present from the compressed air in the tank.
I saw a video of a car that ran on 100% hydrogen where the tank was deliberately breached in a staged accident. It didn't explode. Instead, the hydrogen shot out like a blowtorch, maybe 1 foot long if I remember correctly. If the breach was in your direction, you would be toast. Otherwise the flame would burn itself out ASAP.
