The University of Michigan undertook a study to determine the effects of rain repellent coatings on automotive windshields. Under simulated rainy driving conditions, treated glass:
- Reduced response time - On average greater than 1 second, equivalent to more than 88 feet of travel at 62mph (27m at 100kmh)!
- Significantly increased visual acuity - 34% higher ability to recognize objects, signs and hazards, with night time vision as clear as untreated day time vision
