A few years ago, Tesla became an early mover in the use of a new vehicle manufacturing technique called gigacasting. Using a large casting machine, automakers could now assemble a vehicle's underbody using only a handful of segments, greatly reducing the hundreds of individual components in a traditional car. Because of this, Tesla was able to drastically lower costs and improve production efficiency of the Model Y.
However, people have had understandable concerns about what happens when a Model Y is in a collision. How easy is it to find replacement parts? Are repairs more expensive than traditional manufacturing methods? Is repair work even possible or is your car more likely to be totaled?
