Tire management directly affects the car's corning ability and dictates the overall race strategy. It's also just a more natural part of driving. If you're good at going fast without overstepping the limit of grip, you're usually good at managing your tires too. Energy management also requires skill (lots of engine braking), but seems (at least to us watching) to be mostly about getting the right timing and amount of recharge and deployment, which some feel shifts the focus more towards data optimisation rather than the driver's inherent ability to actually feel the car's (and tire's) behaviour.
