The thing to remember is that we do rather abuse whatever cell tech we are using. Our demands in terms of peak discharge currents especially are far higher than most applications, and then we want rapid recharge too. Stuff like Tesla's spread big currents across many cells in parallel so the individual load is much less and weaker cells arent as stressed.
So if a cell tech IS dangerous we would spot it first, but at the same time we tend to pay more attention to our cells than in other applications where you can't easily spot the tell tale puffing.
