hello,sumo developer，my question is that when i using simpla to create platooning vehicle, the gap becomes larger after the vehicle turns right.Normally, the platoon vehicle spacing should be constant.

gap become larger normal platoon

The connection between the access lane and the main carriageway has a lower speed limit than the neighbour elements due to its angle. If you overwrite the speed limit e.g. in Netedit, neither the leader nor the followers brake and thus the inter-vehicle distance remains constant.

No they aren't. Please check the docs. By default, speed limit is reduced within an intersection depending on the turning radius.
