1. A gesture access system for a motor vehicle having a powered door, the gesture access system comprising:
at least one wireless signal transceiver configured to be mounted to the motor vehicle, the at least one wireless signal transceiver responsive to activation signals to emit wireless signals outwardly away from the motor vehicle, and to produce wireless detection signals, the wireless detection signals including at least one reflected wireless signal upon reflection of at least one of the emitted wireless signals by an object toward and detected by the at least one wireless signal transceiver,
a motor responsive to motor control signals to open the power door,
at least one processor, and
at least one memory having instructions stored therein executable by the at least one processor to cause the at least one processor to (i) process the activation and wireless detection signals to determine whether an object is following a predefined gesture, (ii) upon determining that the object is following the predefined gesture, control an unlocking actuator to unlock and unlatch the powered door, (iii) following unlocking of the powered door, monitor and process the activation and wireless detection signals to determine object parameters including a speed of movement of the object away from, and a distance of the object relative to, the powered door, (iv) determine a door opening speed based on the object parameters, and (v) control the motor control signals to open the powered door at the determined door opening speed.
