Shore Drive appears in the description of the Grotti Cheetah, an Ultimate car that unlocks later in the story. The car is called an ode to this strip, with a sleek retro-futuristic paint job.
The Ultimate text calls the Cheetah 'Grotti's signature mid '90s sports car and ode to Shore Drive,' with a minimalist, retro-futuristic livery that is 'available to punctuate later-stage action.' Rockstar has not described the road itself, and no official map places it yet.
