Why does sending or reading text messages (mensajes de texto / WhatsApp) while driving present a catastrophic crash risk?

1. It drains the smartphone battery too quickly
2. It combines all three primary forms of distraction simultaneously: visual (eyes off the road), manual (hands off the wheel), and cognitive (mind off the driving task)
3. It interferes with the car's tire pressure monitoring radio frequencies
4. It only poses a risk if the vehicle lacks Bluetooth connectivity
