I don’t think we have the convenience of a “smooth transition” We made hard pushes for phasing out oil and the industry and their political puppets block or slow things down to a crawl. Taking it slow as a policy is a great way to make sure nothing happens. Oil companies and auto makers would be pleased as punch if they could even roll back emission standards and green energy incentives.

“How can we turn of the 10,000 gallon per hour waterfall at my house when I still need to drink water?”

Via a managed phase-out.

You can:

• Stop making ICE vehicles.
• Improve public transport
• Encourage the manufacture of ebikes and electric cars.
• Reduce oil extraction

All at once.

I’ll also note that the US is a huge oil exporter. As such, sharply reduced extraction would largely cause pain to the oil industry and overseas.
