You've listed vehicles with significantly higher price points and power outputs (sans RX8), and subsequently are more inclined to offer this peace of mind.
You can continue to ignore sound math and perspectives, though, to make yourself feel better

CFRP propeller shaft.
The new BMW M3 Sedan and new BMW M4 Coupe also feature a CFRP propeller shaft. CFRP’s high rigidity and low weight mean that the drive shaft can be produced as a single-piece component without a centre bearing.
This provides 40 per cent weight savings over the previous model, and the reduction in rotating masses results in sharper throttle response. The use of carbon in these models is a reminder that BMW is a global leader in high-strength, lightweight CFRP construction, and that it was BMW who brought out the first mass-production vehicle with a body consisting entirely of this material – the innovative BMW i3.
