yes in a Petrol car there is a problem with smoke = fire. My whole point is that smoke in a petrol engine usually means something as either caught fire etc. Smoke in a Battery compartment may or may not. Is it a safety issue? Probably, but not definitely. Do the general public have a problem with smoke on a plane? Hell yes. Our experience with traditional cars and planes is that where there is smoke there is fire. That may or may not be true with the batteries, I dont know but I do know that Boeing do a LOT of testing, so would be suprised to see a plane go down due to these problems. I believe the cars you were talking about were completely submerged in sea water and then caught fire. Presumably any car or plane submerged in sea water will get written off which is probably why they dont worry too much about it.
