Electric car fire risk in rental housing

[Kay March]

After reading reports of serious, damaging fires caused by electric car batteries, I'm considering disqualifying potential tenants who have electric cars and putting a clause in my lease prohibiting electric cars and stating that the tenant expressly assumes all risk of damage to the property arising from electric car fires. It's my understanding that these fires are highly unpredictable and there are no reliable prevention measures. Has anyone else taken steps to deal with this risk?
