This isn't about a BMW decision to reduce cost in a luxury car because any cost saving in omitting a spare of any type along with the jack and wrench is more than compensated by the extra cost of RFT and sensors. Every design engineering compromise in new cars must deal with the problem of meeting the relentless pressure of emissions and mpg requirements imposed by governments. Among the performance and brand preserving design engineering compromises that buyers don't like is weight reduction through spare wheel omission. While others have asserted that the weight saved by omitting a spare has been restored in the extra weight of four RFTs over non-RFTs, careful calculation does show a net reduction. However much we buyers may dislike RFT, ASS, and other emissions and mpg compromise technologies, we have to learn to live with them as the inevitable consequences of performance car manufacturers' need to meet the governmental requirements.
