How many of those hooked on 'Drive to Survive' really care about Formula 1?

One Thursday morning in May, the Formula 1 driver Valtteri Bottas was enjoying an alfresco breakfast with his girlfriend, the cyclist Tiffany Cromwell, on the secluded terrace of a Miami South Beach hotel.
It was a last bit of holidays before the start of practice sessions for that weekend’s Miami Grand Prix. Bottas and Cromwell had spent an hour biking along the beach. Now they were sitting under a trellis of bougainvillea, chatting casually in the way that romantic partners do.
