People really need to know their limitations. She obviously is not very skilled at multitasking.
For me I always make reasonable efforts to focus on the road when driving. For example, when binge watching streaming videos, eating lunch on the road, and talking on the cell phone, I will usually use one of these effective strategies:
1. use a cupholder for the drink
2. use bluetooth for the phone call
3. wait until stopping a red light before applying condiments to a burger
Just requires thinking ahead. Duh.
Oh, I left off the most important one...
4. learn to use one hand while texting
This way, when you are taking a bite of your burger or taking a drink, you’ll have at least one free elbow to steer with. All good drivers know that you should not rely on steering with your knees for prolonged periods because you will have trouble maintaining lane position at high speeds.
