According to certain aspects, the electronic device may determine (458) that it is being transported by a vehicle. The electronic device searches or detects (460) nearby WLAN and/or WPAN signals and identifies (464), based on the detected signals, how many devices are nearby the electronic device. The electronic device compares (468) the number of nearby devices to a threshold amount and, based on the comparison, either initiates (472) a public transportation mode or initiates (470) a driving mode. ## Claims ### Claim 1 A method comprising: determining, by an electronic device and based on movement data, that the electronic device is being transported by a vehicle;
