Approximately from this point the speed limit should be 50 km/h according to Mapillary. Is it worth to split up the segment in two and indicate the correct speed?

Approximately from this point till the roundabout junction speed limit should be 50 km/h according to Mapillary. Is it worth to split up the segment in two and indicate the correct speed?

The stretch should have speed limit = 50 km/h according to Mapillary

Is it correct to determine speed limit as 0 km/h? Would it better to delete speed tag and leave motor_vehicle=no, for instance?

Is the tag "motor_vehicle=no" still valid for the stretch?

There is a bridge near. And for the way under it a height limit exist = 4 m according to Mappilary

Is it possible to split up this long way so that for the segment under bridge it would be possible to add max_height tag?
