The new system looks truly wonderful, and I’m very impressed. It even made me feel that I should build not only ships, but more vehicles as well. (that's SimplePlanes✈️)
Since I play this game on mobile, I have been using wheels to build tanks. I understand that SP2 will introduce transmissions and other new features, but I hope the current system—where engines and wheels are essentially connected via Bluetooth, as in SP1 vehicles—will remain available.
Apologies if this is already planned.
