head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Execution · Pure Mechanics
The 70s-cinema getaway driving game with famously demanding physics.

Execution · Practiced Mastery
Track memorisation and upgrade economy layered under straightforward racing execution.
Driver leans Execution (Pure Mechanics); Top Gear 2 leans Execution (Practiced Mastery).
Driver leans a little harder on execution, though the gap is small.
Driver
Handbrake control and pursuit driving by feel
Top Gear 2
Clean cornering and nitro timing decide finishing position
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Driver
Police AI is mappable
Top Gear 2
AI racers follow fixed rubber-band behaviour
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Driver
Traffic adds mild unpredictability
Top Gear 2
Tracks and hazards are identical every championship
Top Gear 2 leans a little harder on optimization, though the gap is small.
Driver
City routes and mission tactics learnable
Top Gear 2
Upgrade purchase order and track memorisation compound advantages
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
