A vehicle having a vehicle body, a seat, an engine, a throttle body, a throttle valve, a throttle valve actuator, a throttle operator, a throttle operator position sensor, a cruise control switch, and a vehicle speed sensor. Said wheels and pinions are all electrically grounded to avoid spark discharges which can be produced by the charging of voltages through frictional electricity. Speaker outlet earpiece is placed near the top of upper housing to keep the user’s ear, head, and brain away from antenna which is placed on the bottom of lower housing. With this structure, a photovoltaic conversion device with high photovoltaic conversion efficiency can be realized. Access logic on the mobile communication device checks another database of PUID Access Policies and Preferences for authorization.
