About Dash & Drive

Who writes this

Sawyer V.. Not a mechanic, not an installer, not a product tester — just somebody genuinely into how this stuff works. I read the manuals, compile the specifications manufacturers actually publish, and do the arithmetic they leave out. Then I tell you what I would fit to my own car and why.

No lab coat, no test bench, no owned units. That is stated plainly here and it is stated again above the first affiliate link on every commercial page, because it is the single most important thing to know about this site before you take a recommendation from it.

Why this site exists

Because the field it competes in is full of testing claims, and almost none of them change the advice. Every serious competitor in this category leads with “we tested twelve” or “lab tested and ranked”, and then ranks products on the same specifications anyone can read off the manufacturer's own page.

There is an obvious gap in that. Nobody publishes the arithmetic. Nobody works out what parking mode actually costs your battery in milliamps, or notices that one dash cam maker publishes a 70 C operating ceiling for its cheap camera and 60 C for its expensive one, or points out that a “67W” charger might cap every port at 35W.

Those are all things you can find by reading published documents carefully and doing division. No lab required. That is what this site does instead of testing, and it is a better fit for what the reader actually needs to decide.

Who it is for

Somebody improving a car they already own. Not a car enthusiast, not somebody researching a purchase for six weeks, not somebody with a project car in a garage. A person who drives to work in a normal car, has noticed two or three things that annoy them about it, has maybe $150 to fix one, and would like to install it themselves on a Saturday without special tools.

That framing decides everything about how pages here are ranked. Install effort is a scored axis rather than a footnote, because half an hour under a dashboard is a real cost to that person. Price is scored against a $150 ceiling rather than against the category. And a published heat ceiling matters more than a resolution figure, because their car sits outside all day at work.

What this site is not

• Not a test lab. Stated everywhere it matters, including above the first affiliate link on every commercial page.
• Not a shop. Nothing is sold here. Links go to retailers and we earn a commission if you buy — the full disclosure is here.
• Not a car enthusiast site. No performance parts, no modifications, no project builds. Everything here is bolt-on, reversible and under $150.
• Not medical advice. The comfort section describes product geometry and materials. It does not diagnose or treat anything.

Where the site is right now

37 pages, 41 products in the ledger, and 6 of those products publishing an operating-temperature ceiling — which is a statistic about the industry rather than about this site, and it is the reason that specification gets so much attention here.

Every specification traces to the manufacturer page or owner's manual it came from, and every one of those sources is linked at the foot of the page that uses it. Where a maker does not publish a figure, the table says “Not published” and the product loses points for it. That is the whole method, and it is written out in full here.

If something here is wrong

Tell me. A wrong specification is the worst thing that can happen on a site whose entire argument is that the numbers are checkable, and a correction gets priority over anything else in the queue.

The contact page is here. A page URL and the figure you believe is correct is enough; a link to the manufacturer page is better. Corrections get a dated note on the page rather than a silent edit — the policy is here.
