Crashing a car is usually not a good idea. But sometimes, it can save lives.

No one ever wants to get in a car crash. But if you ever do, be very thankful for the engineers who crash test cars. You may have seen crash test simulations on TikTok using physics engines like BeamNG but I promise you they are nothing compared to the real thing! Join us for this DEEP dive into the physics of car crashes and the ways that engineers hack Newton's laws to keep you safe.
