air suspension if the car sits too low.
air suspension, but it would have to blow my mind to make me buy it, not just be a slight improvement.
Air Suspension
Way too much optimism about that. Likelihood that Tesla Model 3 come with air suspension is way below 20%.
But maybe adjustable dampers will be available. That doesn't take a lot of space, weight nor engineering resources.
Air suspension is not available even on BMW 5-series, not to mention 3-series.
