Instead of bringing up safety, I'd bring up the microplastics and other pollutants emitted by the technology of the elastomeric tire and which might be an intrinsic property of cost-effective use of the technology.

Sounds like trains are pretty safe to me.
Cars get into accidents way more frequently. The American freight rail system derails at a more frequent rate because the private operators are incentivized to really not do any maintenance at all.
Trains don’t “regularly” derail. And when they do, they aren’t as fatal as the median highway crash.
There are unlikely to be too many fatalities in this system because it runs slowly. (Unless Li-on batteries cascade combust somehow.)
