As far as I know the percentage of hoverboards that catch fire can also be low. It may be just that RC hobbyists usually don't post pictures of their flaming batteries on Facebook with a comment that they are a terrible fire hazard and demand to be taken off the market.

For what anecdotal evidence is worth, I know of one house fire and one car fire due to lithium batteries among the members of my local RC club.
