It's easy to forget that Tesla was made possible almost exclusively through government incentives. This is something that most people seem to have forgotten: Tesla exists because the government created incentive programs that paid in cold hard cash. Musk took advantage of those programs, and Tesla absolutely would not have been nearly as successful (and likely not existed) without it.

This is incredibly overstated. There are "incentives" for all sorts of activities. These incentives were available to all manufacturers. We should have "incentives" to produce electric vehicles and manufacturing in America. Insane not to. And these incentives are often "you would normally have to pay us X million in taxes, but we'll let you pay less". When the alternative is something not being built and no tax revenue, it makes sense. And a lot of subsidies were to buyers of EVs

As much incentive as the oil & gas industry receives?

The government should find ways to strategically invest in developing major industries. The market for them is global and China has/will have a bigger internal market than the US, so without intentional development we'll get a continued industrial consolidation that is bad for the US and the world. I have robotic lawn mowers and vacuum cleaners made by Chinese companies partly because an intentional policy from China's government to grow these capabilities locally.

What was the incentive and was that specific to Tesla?

This is such a braindead take. Ford could have taken advantage of those same EV incentives. Any other new startup could have too. Tesla got nothing special.
