I am afraid of the Dodge Demon, crate or not.

Update, 2:08 p.m.: A Dodge spokesman got back to me with a bit more context. This is from a Demon owner’s manual supplement:

The Demon Crate Powertrain Module (PCM) is not equipped with a speed limiter. This will allow the vehicle to exceed the tire’s speed rating of 168 mph (270 km/h). This could adversely affect the handling and safety of the vehicle. It’s the customer’s responsibility to equip the vehicle with the correct speed rated tires for their use above the speed rating of 168 mph (270 km/h).
