After the hype of autonomous driving, the automotive industry has understood that higher-level autonomy increasingly requires the involvement of AI-based solutions. Nevertheless, current brute-force AI solutions need a tremendous amount of data and are computationally expensive, which leads to the long-tail problem in self-driving and thus the questionable reliability and profitability of AV business. On the other hand, automotive mass-production needs to enhance driver safety and its own sustainability, and to have new products with new technology to attract end users. Younger generations are obsessed with high-tech and want to see more increased autonomy in their vehicles, so many Tier 1s and OEMs are paying great attention to autonomous parking, smart summon, auto-reverse and highway pilot. With the recent technological advancements in automotive SoC, computer vision and robotics, realizing these advanced functions at a great scale is feasible, and thus L2+ is considered a very good intermediate step to leverage the autonomy level.
