Most likely, the first vehicle did not clear up the insertion location
quickly enough for the second vehicle to enter on time *safely*.
Where *safely* is related to the gap that the car following model would
like to maintain at insertion based on the desired insertion speed.
You can disable the safety check by setting vehicle attribute
insertionChecks="none" (see
https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#available_vehicle_attributes
).
