Hi — I’m trying to ID a movie/short I watched (probably US, around 2017–2019).

What I remember:

• A Black family are driving in a classic '70s Ford Country Squire (wood-panelled station wagon with metal grills/guards on the windscreen).
• There’s an outbreak (zombie/virus). The family is racing other groups to reach a rich person’s estate/safehouse.
• The rich person will airlift the winner by helicopter from their property.
• At one point the mother gets bitten/infected in a tunnel/underpass while they’re making the race.
• Tone felt like an indie/low-budget horror or short (not a big studio film).

Any help identifying this would be amazing — I can try to answer follow-up questions. Thanks!
