We show that models with deformations of special relativity that have an energy-dependent speed of light have non-local effects. The requirement that the arising non-locality is not in conflict with known particle physics allows us to derive strong bounds on deformations of special relativity and rule out a modification to first order in energy over the Planck mass.

On the Consistency of Covariant Light-Speed Variation in Doubly Special Relativity
In the DSR1 model with subluminal light-speed variation, a boosted box can overtake its own emitted photon above a critical rapidity, leading to tensions in particle counting and motion not resolved by relative locality.
