In addition, modern tadpoles and delta trikes have a very narrow track, which is fraught with overturning.
The standard track gauge in Russia is 1520 mm, but in some cases it can be less, in the range of 1270-1350 mm.
I chose the smallest 1270 mm.
This will be a very stable bike track.
Not a single passing wagon can knock the rider on my trike out of the saddle with a stream of wind.
