are any plans to improve tractor stations I want to like it but tend to skip it for the Simplicity of belts I don't think we'll ever get around the fact that belts are more simpl, simple to use and set up, we might tweak some of the track like the vehicles and stuff like that but I don't think we'll, spend too much time on it it's it's a bit of like a what's the term like when we we've we've invested so much time in vehicles and, we feel like we're never going to satisfy everyone so like it's our return of investment here is sort of kind of over yes it's a little bit of sun cost valy a little bit with the work that goes into the vehicles cuz like we need to spend so much time working the vehicles to get to make them bet make them a little bit better, and a little bit better and I think we would like to make them a lot better but it's just, we already sell so much time at it and it's better to spend that time on other stuff, we think the vehicles are okay but like I don't think we're- I think the whole thing with satisfactor 2 with that like there are a lot of other logistics Solutions, so you're not so I know some people that just want to use vehicles and like not use trains and not use drones and stuff like that, and, I don't really have an answer to that statement other than than but I think we'll tweak still go tweak a little bit I think there are some issues that we need to solve
