"Faulty" is what I thought too, but no. They are designed that way - I have no idea under what circumstance it needs to vent excess gas but it does. He had the car in his garage where there was also a freezer. When the thermostat clicked on the freezer a spark ignited the gas and ka-boom.
Incidentally petrol/gasoline vehicles are same. I recall seeing a neighbour's car spilling fuel from the filler cap on a freakish hot day. I was OMG OMG but the fire service kind of laughed at me and said well yeah they can do that.
Agree with you that if you can find a suitably large vehicle then the loss of internal space is not so bad.
Incidentally I forgot to mention that when you retrofit the LNG system to a car it is additional to the existing fuel system, not a replacement. This means extended range. My aforementioned mate used to love doing a demo to people where he was driving on the highway and the gasoline tank almost empty then he would flick a switch and the full LNG would kick in seamlessly. He was a bit of a nut that way actually and would drive 500 miles without stopping, just because he could.
I found out about them because I kept glancing at the taxi drivers empty fuel tank during a 3 hour trip. I was thinking surely he has to pull over at this next stop. They are cool having that flip option plus the savings.
