Since you repeatedly use the term "give", it's worth noting that "subsidies" in this case were paid back in full by Tesla:

"Tesla Motors, just cut the government a $451.8 million check, which means that Tesla has paid off its entire Department of Energy loan plus interest. “Following this payment, Tesla will be the only American car company to have fully repaid the government,” the company boasted (emphasis Tesla’s)."
