As for the statement, as a professional I do tend to believe other professionals. Ultimately the statistics don't lie: lithium ion related fires are a minority of current household causes. To your point, that may change over time particularly where larger installations (e-bikes, solar system batteries) are involved. I'll pitch that the regulatory regime is more than capable of catching up and enforcing change if the degree of risk starts to go up. We already see fire departments commenting on it, so it won't be long before we start seeing guidelines and restrictions on battery sizes within homes.
