taking delivery of model X in July or August. From prior experience, very concerned that new sensors for AP 2.0 will appear soon afterwards. I would hope that tesla would put in conduits to run wires later to update to AP 2.0 hardware. Knowing there is an upgrade path that would not involve selling a just purchased car would be reassuring to potential customers. Otherwise I face decision of cancelling order (2500 deposit small fee to avoid trading in a recently purchased car).
