Craftable Passenger Cars and Player-Made Asphalt Roads

Into the world of "Advanced Realism": Balanced, craftable passenger cars and open utility vehicles (quads/tractors) should be natively added. To preserve absolute building freedom, no roads are pre-generated. Players must manually design and build their own smooth asphalt or stone driveways. Driving on natural blocks like grass or sand drastically drops your vehicle's speed, making custom road construction a highly rewarding infrastructure gameplay loop.
