Final answer:
To remove dangerous old drivers from the road, driving simulation tests, incentives for safe driving, use of public transportation, and stricter licensing policies can be introduced.
Step-by-step explanation:
Other than changing the alpha level for bad drivers, several measures can be taken to remove dangerous old drivers from the road. These measures include: introducing driving simulation tests, which can help assess a driver's ability to handle various road scenarios in a controlled environment; offering incentives for safe driving, which might encourage older drivers to adopt safer driving habits or voluntarily reduce their driving; encouraging public transportation use, as an alternative to personal driving, which can reduce the number of potentially dangerous drivers on the road; and implementing stricter licensing policies, such as more frequent renewals or mandatory retesting for elderly drivers to ensure they still possess the necessary skills to drive safely.
