Lasers require precision optics, so how would you keep laser ignition systems clean (from getting fouled up)? Perhaps the combustion chamber of the cylinder (or whatever) is heated up externally by the laser? Even then the laser would have to be almost powerful enough to burn through the material, so an aluminum block would not work. Anyway it's an idea that's probably been floated in the materials and mechanical engineering fields for years, but the cost of creating an engine that works could be prohibitive.
Here's another "what if?" scenario: Wolverine vs Wonder Woman
