I think this is a good question. You can drive around the city on a bike, so why can't we do the same on foot? Animations can't be that much different on bikes compared to feet and they apparently will have the animations already done for all the reflections, so why not just give us the TPP walking mode? We get it, dialogue and combat is in first person so just make it jump to first person when we get into a combat scenario or dialogue scenario. This doesn't really make a whole lot of sense to me.
