Road that create multiple TSU

[j3r3m1]

We used to use the road network mainline to split the territory, which for the cases of highway or multiple lanes could lead to several TSU next to each other but being super long and super thin.
Now that the road surface is itself a TSU, we still have this behavior:

It might be detail but I wonder whether we could merge the roads intersecting each other could make it better (less super long TSU) ? @ebocher what do you think ?
