NFS lock and unlock. GPS locator. Capacitance touchscreen controls. Hydraulic disc brakes.
Companion helmet with wirelessly connected brake lights, and noise cancelling(?!) speakers.
Why do we need to learn the same lessons over and over again?
That said a GPS locator is great on an e-bike. They're high value theft targets, anything that makes them harder to steal, easier to track, or otherwise reduces the appeal of stealing one is a good thing.
Hydraulic disc brakes are a great thing even on non-electronic bikes. I won't buy another bike without them. My hardtail mountain bike, gravel bike, and e-cruiser are all hydraulic discs.
