Most states already have annual flat fees in place for hybrids and EVs. (Page 35)
TxDOT considered different approaches to making up for the lost state fuel tax (ex. mileage-based) but settled on a flat fee. (Page 36)
Based on their assumptions, an equivalent conventional gas light duty vehicle produces $103 in state fuel taxes per year. (Page 27)
Instead of imposing a $100 annual fee based on those assumptions, Texas decided to double the fee to $200. This was probably chosen simply because it was the most common highest fee imposed by other states.
California and Illinois only charge an additional $100, Colorado $50, Oregon $150, and Washington $150.
One thing I have to do for my employer is ensure that our websites and products are 508 compliant. Basically, making sure our product is accessible to people with disabilities. So, I have to test them using the following tools:
ZoomText – for the vision impaired
JAWS (Job Access With Speech), also for vision impairment
Dragon Naturally Speaking – speech recognition software for those with physical impairments, so you control things with your voice.
