A modular system for an automotive vehicle configured to permit removal of a removable structural module from and reattachment to an automotive vehicle is described. The system includes a removable structural module comprising a body, a support structure configured to receive and support the removable structural module and to permit the removable structural module to be releasably attached to an automotive vehicle, a sensing arrangement configured to permit confirmation of secure attachment of the removable structural module to the automotive vehicle and configured to permit identification of a predetermined type of the removable structural module, and a computer configured to identify the predetermined type of the removable structural module from among multiple possible predetermined types of removable structural modules. The removable structural module comprises multiple connecting structures that permit the removable structural module to be releasably secured to the automotive vehicle.

Utilization of shared vehicles that are structurally and reversibly reconfigurable to suit requests for particular vehicle configurations is described. Vehicle use is monitored for plural vehicles shared among multiple users/uses. In response to a first request for a first particular configuration of a vehicle, a first vehicle is selected/provided in the first particular configuration having a predetermined first feature set, the first feature set being automatically set based on the first vehicle being placed in the first particular configuration. In response to a second use request for a second particular configuration of a vehicle different from the first particular configuration, the first vehicle is selected/provided in the second particular configuration having a predetermined second feature set, the second feature set being automatically set at the first vehicle based on the first vehicle being placed in the second particular configuration, the first feature set being different from the second feature set.

The invention relates to a brake shoe (1) for disk or drum brakes, which comprises a supporting plate (2) with a friction pad (3) attached thereto and at least one wear indicator (4), characterized in that the wear indicator (4) has a wear sensor (6) for continuous or multi-stage measurement of the wear of the friction lining and a receiver and transmitter unit (5) for wireless signal transmission, the receiver and transmitter unit being a passive RFID (Radio Frequency Identification) or SAW (Sound Acoustic Wave) transponder.
