Thank you for the point. Hopefully you enjoyed Antwerp :-)
Last year there has been a tragic accident with one of these Stints in the Netherlands. 4 children died during that fatal accident. (These Stints can be seen as kind of a small Segway truck, and they were initially constructed to transport small children). Since the accident, these vehicles were no longer allowed in traffic in the Netherlands and certain towns in Belgium , but maybe the utility versions are still allowed.
