Hmm, I might try to add a roller out in front of my flat ram next time I find one, might help in gaining entry.
When I’ve hit something moving quickly, it tends to move in a straight line away from center of mass, but sometimes when I’m pushing cars slowly the front will “kick out” briefly like it’s trying to turn but can’t. I’m definitely gonna build a wedge vehicle soon to test.
Most of the time, I don’t need to push stuff out of the way, it’s just convenient so I can get back and forth faster. CBMs do seem to work well, but most options require stopping and getting out which I’m trying to not have to do. I can cut through ~6 forest tiles at 20mph before having to repair (pretty sure it’s faster than fire for a straight line, when I’m feeling brave I’ll set a forest on fire and try to drive next to it to test) and hordes barely put a dent on my forward speed due to high mass and lots of engines (5x10 with a 7x2 ram on the front). Cars, especially on long bridges, are the main issue here. Trying to push them will move them parallel to the bridge until their wheels break off most of the time instead of out of my way. I also just love the image of clearing a road with some school bus that has a huge metal wedge welded to the front.
On a side note, did you know you can place rams in front of other rams? As long as the front row has one connection to the main vehicle you can delete the frames behind them, and other rams count as connections. This means you can place the front row and replace the frames behind them with rams, or overlap your rams past the edge of your vehicle! I know it’s probably a bug, but with the extra time it takes to install it seems balanced enough (it take 45 extra minutes per ram if the frame used is an extra light).
