Tariffs and E.V. adoption are two major headwinds facing the auto industry. Karl Brauer discusses the impact of tariff uncertainty on car sales and inventory. Despite initial demand surges, Brauer expects a pullback in May, citing "pull forward" sales and inventory normalization. E.V. adoption also lags behind expectations due to range anxiety, limited charging infrastructure, and higher upfront costs. General Motors (GM), Tesla (TSLA) and other E.V. pure-plays may feel the sting of waning consumer interest.
