tunnel vision

1. What Mr. Happy has (i.e., his "vision" is always focusing on just one thing --- specifically, a gal's "love-tunnel").
2. What the vengeful and intently-gazing-straight-ahead Biff Tannen was experiencing while trying to run down Marty McFly in the underground causeway, and therefore he never noticed Old Man Jones' fertilizer-truck in time to avoid colliding with it --- yet again --- and consequently having himself and his car covered with the truck's messy contents ("MANURE!! I hate MANURE!") a second time, mere hours after having gotten said beloved jalopy back from Terry's garage which had cleaned it out from its previous encounter with said poop-hauler.

I always slow down a bit and drive extra-carefully through mountain-tubes and other underground traffic-passes, since it's notoriously easy to unwittingly get "tunnel vision" when traversing said claustrophobic motoring-routes.

Quantum Tunneling

Quantum tunneling refers to the phenomenon in quantum mechanics where a particle has a finite probability of crossing through an energy barrier or potential barrier despite lacking the necessary energy to overcome it based on classical physics. This behavior arises due to the wave-like nature of particles at the quantum level. Quantum tunneling allows particles to "tunnel" through barriers, enabling them to reach regions that would be classically inaccessible.

"In quantum computing, qubits can exploit quantum tunneling to tunnel through energy barriers, facilitating more efficient computation processes."
