A post on FB (so people need to check the accuracy if this affects them) states that Montenegro will not take EVs and Hybrids on Ro-Ros - and the writer thought this will spread to other ferry companies. He stated that it follows a recent vehicle fire based on the storage batteries.
Yes well, to me it sounds a bit like the early bans on motorized vehicles in favour of horse-drawn carriages. It'll go away, at the latest once people abandon their carriages in sufficient numbers. But yeah, I read about them bans before, for a ferry operating from Batangas. Edit: I just read about the suspicions surrounding the horrible ferry accident. Obviously if those suspicions are confirmed that would be a very sad aspect of the accident, and I didn't intend to diminish the impact of the accident. However, if it would be a statistically big risk related to ev's on boats, then how on earth do they manage such risks on the boats that carry 5,000 or more ev's at once across the oceans. Edit 2. Upon further reading, it appears that carriers demand a SOC (state of charge) between 30 and 50% for EV's on oceangoing ships, following the accident last year in the Pacific in which the Morning Midas, a car carrier sank with around 750 ev's/hybrids on board.
Adding to those fears, I read somewhere (n0t 0n FB ) the extra weight EV's carry in batteries, in the event of a bumper to bumper traffic jam, some bridges would strain to carry such loads!
