Let's refresh memories, "covered car park fire safety guidance for EV" was the report: https://www.briskoda.net/forums/topic/517208-car-park-fires-transporters-ships-any-fires-any-evs-involved-or-not-thread-were-they-the-cause-just-there-and-so-made-fighting-the-fire-harder/page/6/#findComment-5804476 The data on page 21 came from Thatcham Research and MIAFTR. " Thatcham Research, the UK motor insurers’ research centre, used the data from the Motor Insurance Anti-Fraud and Theft Register (MIAFTR) and their own data to categorise fire claims by vehicle fuel type, excluding claims relating to theft as they could be due to arson. " First, this number did not come from fire departments. Second, previously you talked about Thatcham Research, where it supported your views, you claimed they were very reputable. The number that kept being quoted is because that's the only stat available. Until you've got more reputable stats, casting doubt on reputable figures seems to have arterial motive.
