Can the government mechanically force you to wear your seatbelt? [w/poll]

The National Highway Traffic Administration is considering the use of ignition interlocks in vehicles that would require the seatbelts of occupied seats to be fastened in order to drive the car, Automotive News reports, four decades after Congress moved to prevent manufacturers from installing them in cars sold in the US market. Following a transportation bill passed last year that lift some of the restrictions on seatbelt interlocks, automakers such as BMW are considering the benefits of using them in future cars. Now, before you go crying about your lost freedom, keep reading.
BMW said in an October 2012 petition that the use of seatbelt interlocks would allow the company to make lighter and more spacious vehicles, if the devices could be used in lieu of unbelted crash tests. The crash test has required the addition of bulky safety features, such as knee bolsters, that aren't as necessary when occupants are buckled up, especially when considering the dizzyng list of safety features that come standard on today's cars. Europe, which has a higher rate of seatbelt use than in the US, doesn't perform unbelted crash tests on cars sold there.

2014 BMW X5

Is Better Than Ever Still Good Enough?
By now, all but the staunchest of traditionalists have moved past the shock and horror of seeing their favorite automotive brands branching into categories and segments that break with their previously accepted norms. In other words, you and I don't really care all that much if the BMW M3 is powered by an inline six or a V8, or whether it boasts a turbocharger, just so long as the end result is an awesome car. Similarly, we don't get all hot under the collar seeing that same M3 share space on the showroom floor with a brace of SUVs and crossovers... or, as BMW continues to insist, Sports Activity Vehicles.
Time, as they say, heals all wounds, and the BMW X5 has been around long enough, having first seen the light of day in 1999, that anyone offended by its existence has since gotten over it. Plus, the X5 is a legitimately nice vehicle to drive, offering such desirable qualities to family men and women as seating for up to seven, all-wheel drive and a commandingly tall view of the road. For the enthusiast set, the X5 serves up a taut chassis and powerful engine options.

BMW to offer carbon fiber wheels in a year or two

The Citroën SM sat on the first set of production glass fiber and resin wheels in 1972 when parent company Michelin developed the exotic hoops in order to take the SM rallying. It wasn't until 2008 that we got the first all-carbon-fiber wheel for passenger cars in the form of a prototype model from Weds Sports in Japan that remained a prototype. Australian company Carbon Revolution followed that a year later with its CR-9 all-CF wheel, first introduced on the Shelby Ultimate Aero and now available for independent purchase for about $15,000 per set. BMW could be the first OEM to offer entire wheels in carbon fiber reinforced plastic in two years.
The wheels - either all-CFRP or using a CFRP rim and alloy spokes - were shown off during BMW's Innovation Days in Munich and are products of the development work done on its i-branded cars. The full-CFRP wheel is 35-percent lighter than a forged alloy wheel, the hybrid alloy and CFRP wheel is 25-percent lighter, making for a decent drop in unsprung rotating weight. As demonstrators during a tech day the wheels aren't yet in the pipeline for production and EU approval, but an article in Auto Express claims that they could be on the market as soon as two years from now.
Other possible parts include a full carbon fiber steering wheel and propeller shaft, the latter of which is coming as a single-piece component on the new M3 and M4. BMW is also talking up its use of secondary carbon fiber - waste material from i3 and i8 production - that can be used for items like IP support structures, seat frames and spare wheels in place of traditional metals like aluminum and magnesium. There's an excerpt of the Innovation Day press release below with more details.
