I've secured multiple podiums and a pole position, but never a race victory. My career has spanned across several teams, including one famously known for its British racing green cars. Despite my consistent performances, I'm often cited for being almost there but not quite. Who am I?

1. I was teammates with a multiple time world champion.
2. I'm known for my calm and composed demeanor in the cockpit.
3. I've had stints in both a works and a customer team of a specific engine supplier.
4. I am a driver of the 21st century
