Methods and systems for a complete vehicle ecosystem are provided. Optionally, the supporting arm is pivotally attached to a to the vehicle mountable fastening part. The apparatus also has a probe carried on the distal end and defining a contact surface that may be urged against the patient region thereby creating contact pressure. The lift coefficient CL at Re 700002000 rpm may be at least about 70 percent of the lift coefficient CL at Re 800002000 rpm, and the drag coefficient CD at Re 1800002520 rpm is up to about 0. To the base plate sustain block is mounted with recesses and openings, also housings with fine tuning springs, contacting with the respective rear string saddle.
