Vectrix Hazard Lights

Vectrix Hazard Lights - or rather the lack thereof!

The official Vectrix manual recommends deep discharges by driving the Vectrix on the road.

At the end of a "deep discharge ride" the scooter is strictly speaking not roadworthy, cannot accelerate normally, cannot travel uphill, cannot go faster than maybe 40km/h on a flat road....

I think it would be a requirement to use hazard lights under such circumstances!

Of course, there are all the usual uses for hazard lights on vehicles as well.

Why does the Vectrix VX1 not have them?

How can it be fixed?
