LPG tanks in vehicles are far safer than petrol tanks.
Which is more crash-proof? A metal tank made of 5mm thick steel bolted to brackets welded into the frame of the vehicle, or a leaky plastic bucket tied underneath with a couple of straps?
- toast0 4y agoStress of fueling is probably a bigger deal than crash resistance. Most vehicles never get into a collision, and very few get into a collision where the integrity of fuel storage is an issue, but most are fueled often. I've never seen a gasoline or diesel station have enforced safety requirements, but when I was looking at CNG cars, PG&E required pre-registration to access their fueling station, with a required fuel system safety inspection (which you can't pass with an expired tank) and a safety video. And it would be very inconvenient to drive through California without using their fueling stations. Meanwhile, gasoline stations often run unattended, with no registration or safety inspection.
