Wentward pneumatics

I've been doing bus routes again and unfortunately it's a little bit painful to do them right now because of constant low pressure. It feels like pneumatics system is simplified in Wentward right now. Usually buses have 4 main air tanks: one for front brakes, one for rear brakes, one for parking/emergency brakes and one for suspension and doors. However in game it looks like it have only two of them based on the gauges. Rear air tank is for rear brakes, suspension and parking brake where front one is for front brakes and doors. This creates massive issues on Beam short routes, sometimes full of hills that requires using brakes all the time because bus doesn't have a retarder. On top of that refilling the air taking ages, because of safety systems cutting off the throttle and idle mode isn't implemented yet. Is this going to be improved in the future?
