Is there any existing method to spawn a vehicle giving a global longitudinal position?

[lev-smolentsev-K1]

For now, I see it by manually iterating by block & each lane calculating the total length and comparing with desired longitude of a vehicle. Am I missing some existing method?

I think it is allowed to generate vehicles by filling in the global position and heading as the argument:

metadrive/metadrive/component/vehicle/base_vehicle.py

Line 121 in 05ec6c8

position=None,

The reason we calculate the lane length for lanes in each block and place vehicles is that we want to scatter vehicles on the map evenly or randomly and avoid overlapping.

Thanks for your reply! My reason is that I want to spawn a traffic vehicle in predefined longitude on the predefined map (being a sequence of S or C segments). I achieved that by iterating over each block and checking the length of the road.
