>>1394417Found out it was abandoned in 2013 due to safety concerns, never used in commercial operation, which was planned for 2015.
ASA Seaside Railway on the Shikoku island plans to introduce DMVs in 2020.

Overall, it's very niche and road-rail vehicles haven't been used much successfully, outside of maintenance vehicles.
I don't think it's going to work commercially, because roads are free to use, but railways, even if unused, usually have an operator that would want to charge for their use.
